ad8418 data sheet theory of operation the ad8418 is a sin gle - supply, zero drift, difference amplifier that uses a unique architecture to accurately amplify small differential current shunt voltages in the presence of rapidly changing co m mon - mode voltage s . in typical applications, the ad8418 is used to measure current by amplifying the voltage across a shunt resistor connected to its inputs by a gain of 20 v/v ( see figure 26) . the ad8418 is designed to provide excellent common - mode rejectio n, even with pwm common - mode inputs that can change at very fast rates, for example, 1 v/ns . the ad8418 contains patented technology to eliminate the negative effects of such fast changing external common - mode variations. the ad8418 features an input offset drift of less than 500 nv/c . this performance is achieve d through a novel zero drift architectur e that does not compromise band width, which is typically rated at 2 50 khz. the reference inputs, v ref 1 and v ref 2, are tied through 100 k? resistors to the positive input of the main amplifier, which allows the outpu t of fset to be adjusted anywhere in the output operating range. the gain is 1 v/v from the reference pins to the output when the reference pins are used in parallel. when the pins are used to divide the supply, the gain is 0.5 v/v. the ad8418 offers breakthrough performance without compromising any of the robust application needs typical of solenoid or motor control. the ability to reject pwm input common - mode voltages and the zero drift architec ture provid ing low offset and offset drift allow s the ad8418 to deliver total accuracy for these demanding applications. + i shunt g = 20 v cm = ?2v to +70v v s = 2.7v to 5.5v v ref 1 v ref 2 out 0v v s v s /2 v out i shunt emi filter emi filter v cm 0v 70v ad8418 v s +in ?in ? gnd ?50a 50a r shunt 1 1546-225 figure 26 . typical applic ation rev. 0 | page 10 of 16
data sheet ad8418 output offset adjustment the output of the ad8418 can be adjusted for unidirectional or bidirectional operation. unidirectional opera tion unidirectional operation allows the ad8418 to measure cu r rents through a resistive shunt in one direction. the basic modes for unidirectional operation are ground reference d ou t put mode and v s referenced output mode. for unidirectional operation, the output c an be set at the negative rail (near ground) or at the positive rail (near v s ) when the differential input is 0 v. the output moves to the opposite rail when a correct polarity differential input voltage is applied. the r e quired polarity of the different ial input depends on the output voltage setting. if the output is set at the positive rail, the input polarity needs to be negative to move the output down. if the output is set at ground, the polarity must be positive to move the ou t put up. ground refere nced output when using the ad8418 in this mode, both reference d inputs are tied to ground, which causes the output to sit at the negative rail when there are zero differential volts at the input (see figure 27). ? + r1 out gnd v s v ref 1 v ref 2 ad8418 r2 r3 r4 ?in +in 1 1546-025 figure 27 . ground referenced output v s referenced output this mode is set when both reference pins are tied to the positive supply. it is typically used when the diagnostic sche me r e quires detection of the amplifier and the wiring before power is applied to the load (see figure 28). ? + r1 out gnd v s v ref 1 v ref 2 ad8418 r2 r3 r4 ?in +in 1 1546-026 figure 28 . v s referenced output bidirectional operat ion bidirectional operation allows the ad8418 to measure currents through a resistive shunt in two directions. in this case, the output is set anywhere within the output range. typically, it is set at half - scale for equal range in both dir ections. in some cases, however, it is s et at a voltage other than half scale when the bidirectional current is nonsymmetrical. adjusting the output is accomplished by applying voltage(s) to the reference d inputs. v ref 1 and v ref 2 are tied to internal resis tors that connect to an internal offset node. there is no operational difference between the pins. rev. 0 | page 11 of 16
ad8418 data sheet external reference d output tying both pins together and to a ref erence produces an output equal to the reference voltage when there is no differe ntial input (see figure 29 ). the output moves down from the reference vol t age when the input is negative , relative to the ? in pin , and up when the input is positive , relative to the ? in pin. ? + r1 out gnd v s v ref 1 v ref 2 ad8418 r2 r3 r4 ?in +in 2.5v 1 1546-027 figure 29 . external reference d output splitting the supply by tying one reference pin t o v s and the other to the ground pin, the output is set at half of the su pply when there is no di f ferential input (see figure 30 ). the benefit is that an external reference is not required to offset the output for bidirectional current measurement. t ying one reference pin to v s and the other to the ground pin creates a midscale offset that is rat i ometric to the supply, which means that if the supply increases or decreases , the output remains at half the supply. for exa m ple, if the supply is 5.0 v, the output is at half scale or 2.5 v. if the su p ply increases by 10% (to 5.5 v), the output goes to 2.75 v. ? + r1 out gnd v s v ref 1 v ref 2 ad8418 r2 r3 r4 ?in +in 1 1546-028 figure 30 . split supply splitting an externa l reference the internal reference resistors can be used to divide an external reference by 2 with an a c curacy of app roximately 0.5% . splitting an external reference can be done by connecting one v ref x pin to ground and the other v ref x pin to the reference (see figure 31). ? + r1 out gnd v s v ref 1 v ref 2 ad8418 r2 r3 r4 ?in +in 5v 1 1546-029 figure 31 . split external refe rence rev. 0 | page 12 of 16
data sheet ad8418 applications information motor control 3 - phase motor control the ad8418 is ideally suited for monitoring current in 3 - phase motor applications. the 2 50 khz typical bandwidth of the ad8418 allows instantaneous current monitoring. additionally, the typical low offset drift of 0.1 v/c means that the measurement error bet ween the two motor phases is at a minimum over temperature . the ad8418 rejects pwm input common - mode voltages in the ? 2 v to + 70 v (with a 5 v supply) range. monitoring the current on the motor phase allows sampling of the current at any point and provi de s diagnostic information such as a short to gnd and battery. refer to figure 33 for the typical phase current measurement setup with the ad8418 . h - bri dge motor control another typical application for the ad8418 is as part of the control loop in h - bridge motor control. in this case, the shunt resistor is placed in the middle of the h - bridge so that it can accurately measure current in both directions by using the shunt available at the motor (see figure 32 ). using an amplifier and shunt in this location is a better sol u tion than a ground referenced op amp because ground is not typically a stable reference voltage in this type of applic a tion. the instability of the ground reference causes inaccuracies in the measur e ments that c an be made with a simple ground referenced op amp. the ad8418 measures current in both directions as the h - bridge switches and the motor changes direction. the output of the ad8418 is configured in an external referenced bidire c ti onal mode (see the bidirectional operation section). ad8418 +in shunt mo t or v ref 1 v s out ?in gnd 5v controller v ref 2 nc 5v 2.5v 1 1546-030 figure 32 . h - bridge motor control ad8418 bidirectiona l current measurement rejection of high pwm common-mode vo lt age (?2v t o +70v) amplific a tion high output drive ad8214 inter f ace circuit v+ i u i v i w v? optiona l p art for overcurrent protection and f ast (direct) shutdown of power s t age ad8418 controller 5v 5v m 1 1546-031 figure 33 . 3 - phase motor control rev. 0 | page 13 of 16
ad8418 data sheet solenoid c ontrol high - side current sense wit h a low - side switch in th e case of a high - side current sense with a low - side switch , the pwm control switch is ground referenced. an inductive load (solenoid) is tied to a power supply. a resistive shunt is placed between the switch and the load (see figure 34 ). an advantage of placing the shunt on the high side is that the e ntire current, including the re circulation current, can be measured because the shunt remains in the loop when the switch is off. in addition, diagnostics can be enhanced because shorts to ground can be detected with the shunt on the high side . in this circuit configuration, when the switch is closed, the common - mode voltage moves down to near the negative rail. when the swit ch is open, the voltage reversal acro ss the i n ductive load causes the common - mode voltage to be held one diode drop above the battery by the clamp diode. ?in 1 gnd 2 v ref 2 3 nc 4 +in 8 v ref 1 7 v s 6 out output 5v inductive load clamp diode battery switch shunt nc = no connect. + ? 5 ad8418 1 1546-032 figure 34 . low - side switch high - side current sense with a high - side switch th e high - side current sense with a h igh - side switch configuration minimizes the possibility of unexpected solenoid activation and excessive corrosion (see figure 35 ). in this case, both the switch and the shunt are on the high side. when the switch is off, the batte ry is remove d from the load, which prevents damage from potential shorts to ground while still allowing the recirculating current to be measured and to pr o vid e diagnostics. removing the power supply from the load for the majority of the time minimizes the corrosive effects that c an be caused by the differential voltage between the load and ground. when using a high - side switch, the battery voltage is connected to the l oad when the switch is closed, causing the common - mode voltage to increase to the battery voltage. in this case, when the switch is open, the voltage reversal across the i n ductive load causes the common - mode voltage to be held one diode drop below ground by the clamp diode. ?in 1 gnd 2 v ref 2 3 nc 4 +in 8 v ref 1 7 v s 6 out output 5v inductive load shunt clamp diode battery switch nc = no connect. + ? 5 ad8418 1 1546-033 figure 35 . high - side switch high rail curren t s ensing in the high rail, current sensing configuration, the shunt resistor is referenced to the battery. high voltage is present at the inputs of the cu rrent sense amplifier. when the shunt is battery referenced , the ad8418 produces a linear ground referenced analog output. additionally, the ad8214 can be used to provide an overcurrent detection signal in as little as 100 ns (see figure 36 ). this feature is useful in high current systems where fast shutdown in overcurrent conditions is essential. v s 1 +in 2 v reg 3 nc 4 ?in 8 nc 7 gnd 6 out output overcurrent detection (<100ns) 5v shunt inductive load switch clamp diode battery + ? 5 ad8214 nc = no connect. ?in 1 gnd 2 v ref 2 3 nc 4 +in 8 v ref 1 7 v s 6 out 5 ad8418 top view (not to scale) 1 1546-034 figure 36 . high rail current sensing rev. 0 | page 14 of 16
