GENERAL DESCRIPTION
NC = NO CONNECT
The OP90 is a high performance, micropower op amp that operates from a single supply of 1.6 V to 36 V or from dual supplies of 0.8 V to 18 V. The input voltage range includes the negative rail allowing the OP90 to accommodate input signals down to ground in a single-supply operation. The OP90's output swing also includes a ground when operating from a single-supply, enabling "zero-in, zero-out" operation. The OP90 draws less than 20 A of quiescent supply current, while able to deliver over 5 mA of output current to a load. The input offset voltage is below 150 V eliminating the need for
external nulling. Gain exceeds 700,000 and common-mode rejection is better than 100 dB. The power supply rejection ratio of under 5.6 V/V minimizes offset voltage changes experienced in battery-powered systems. The low offset voltage and high gain offered by the OP90 bring precision performance to micropower applications. The minimal voltage and current requirements of the OP90 suit it for battery and solar powered applications, such as portable instruments, remote sensors, and satellites.

-18V
The OP90 can be operated on a minimum supply voltage of 1.6 V, or with dual supplies 0.8 V, and draws only 14 pA of supply current. In many battery-powered circuits, the OP90 can be continuously operated for thousands of hours before requiring battery replacement, reducing equipment down time and operating cost. High-performance portable equipment and instruments frequently use lithium cells because of their long shelf-life, light weight, and high-energy density relative to older primary cells. Most lithium cells have a nominal output voltage of 3 V and are noted for a flat discharge characteristic. The low-supply voltage requirement of the OP90, combined with the flat discharge characteristic of the lithium cell, indicates that the OP90 can be operated over the entire useful life of the cell. Figure 1 shows the typical discharge characteristic of a 1Ah lithium cell powering an OP90 which, in turn, is driving full output swing into a 100 k load.

In single-supply operation, the OP90's input and output ranges include ground. This allows true "zero-in, zero-out" operation. The output stage provides an active pull-down to around 0.8 V above ground. Below this level, a load resistance of up to 1 M to ground is required to pull the output down to zero. In the region from ground to 0.8 V, the OP90 has voltage gain equal to the data sheet specification. Output current source capatibility is maintained over the entire voltage range including ground.

APPLICATIONS Battery-Powered Voltage Reference

Input Voltage Protection
The OP90 uses a PNP input stage with protection resistors in series with the inverting and noninverting inputs. The high breakdown of the PNP transistors coupled with the protection resistors provides a large amount of input protection, allowing the inputs to be taken 20 V beyond either supply without damaging the amplifier.
Offset Nulling
The circuit of Figure 6 is a battery-powered voltage reference that draws only 17 A of supply current. At this level, two AA cells can power this reference over 18 months. At an output voltage of 1.23 V @ 25C, drift of the reference is only at 5.5 V/C over the industrial temperature range. Load regulation is 85 V/mA with line regulation at 120 V/V. Design of the reference is based on the bandgap technique. Scaling of resistors R1 and R2 produces unequal currents in Q1 and Q2. The resulting VBE mismatch creates a temperature proportional voltage across R3 which, in turn, produces a larger temperature-proportional voltage across R4 and R5. This voltage appears at the output added to the VBE of Q1, which has an opposite temperature coefficient. Adjusting the output to l.23 V at 25C produces minimum drift over temperature. Bandgap references can have start-up problems. With no current in R1 and R2, the OP90 is beyond its positive input range limit and has an undefined output state. Shorting Pin 5 (an offset adjust pin) to ground, forces the output high under these conditions and ensures reliable start-up without significantly degrading the OP90's offset drift.
V+ (2.5V TO 36V)
The offset null circuit of Figure 4 provides 6 mV of offset adjustment range. A 100 k resistor placed in a series with the wiper of the offset null potentiometer, as shown in Figure 5, reduces the offset adjustment range to 400 V and is recommended for applications requiring high null resolution. Offset nulling does not affect TCVOS performance.

Single Op Amp Full-Wave Rectifier 2-WIRE 4 mA TO 20 mA CURRENT TRANSMITTER
Figure 7 shows a full-wave rectifier circuit that provides the absolute value of input signals up to 2.5 V even though operated from a single 5 V supply. For negative inputs, the amplifier acts as a unity-gain inverter. Positive signals force the op amp output to ground. The 1N914 diode becomes reversed-biased and the signal passes through R1 and R2 to the output. Since output impedance is dependent on input polarity, load impedances cause an asymmetric output. For constant load impedances, this can be corrected by reducing R2. Varying or heavy loads can be buffered by a second OP90. Figure 8 shows the output of the full-wave rectifier with a 4 Vp-p, 10 Hz input signal.

The current transmitter of Figure 9 provides an output of 4 mA to 20 mA that is linearly proportional to the input voltage. Linearity of the transmitter exceeds 0.004% and line rejection is 0.0005%/volt. Biasing for the current transmitter is provided by the REF-02EZ. The OP90EZ regulates the output current to satisfy the current summation at the noninverting node:

giving a full-scale output of 20 mA with a 100 mV input. Adjustment of R2 will provide an offset trim and adjustment of R1 will provide a gain trim. These trims do not interact since the noninverting input of the OP90 is at virtual ground. The Schottky diode, D1, prevents input voltage spikes from pulling the noninverting input more than 300 mV below the inverting input. Without the diode, such spikes could cause phase reversal of the OP90 and possible latch-up of the transmitter. Compliance of this circuit is from 10 V to 40 V. The voltage reference output can provide up to 2 mA for transducer excitation.

Micropower Voltage-Controlled Oscillator
Two OP90s in combination with an inexpensive quad CMOS switch comprise the precision VCO of Figure 10. This circuit provides triangle and square wave outputs and draws only 50 A from a single 5 V supply. A1 acts as an integrator; S1 switches the charging current symmetrically to yield positive and negative ramps. The integrator is bounded by A2 which acts as a Schmitt trigger with a precise hysteresis of 1.67 V, set by resistors R5, R6, and R7, and associated CMOS switches. The resulting output of A1 is a triangular wave with upper and lower levels of 3.33 V and 1.67 V. The output of A2 is a square wave with almost rail-to-rail swing. With the components shown, frequency of operation is given by the equation: fOUT = VCONTROL (V ) x 10 Hz / V but this is easily changed by varying C1. The circuit operates well up to a few hundred hertz.

tions. Nonlinearity is less than 0.1% for gains of 500 to 1000 over a 2.5 V output range. Resistors R3 and R4 set the voltage gain and, with the values shown, yield a gain of 1000. Gain tempco of the instrumentation amplifier is only 50 ppm/C. Offset voltage is under 150 V with drift below 2 V/C. The OP90's input and output voltage ranges include the negative rail which allows the instrumentation amplifier to provide true "zero-in, zero-out" operation.

The simple instrumentation amplifier of Figure 11 provides over 110 dB of common-mode rejection and draws only 15 A of supply current. Feedback is to the trim pins rather than to the inverting input. This enables a single amplifier to provide differential to single-ended conversion with excellent common-mode rejection. Distortion of the instrumentation amplifier is that of a differential pair, so the circuit is restricted to high gain applicaC1 +5V R1 VCONTROL 200k R2 200k R3 100k 75nF

Single-Supply Current Monitor
V+ + TO CIRCUIT UNDER TEST - ITEST
Current monitoring essentially consists of amplifying the voltage drop across a resistor placed in a series with the current to be measured. The difficulty is that only small voltage drops can be tolerated and with low precision op amps this greatly limits the overall resolution. The single supply current monitor of Figure 12 has a resolution of 10 A and is capable of monitoring 30 mA of current. This range can be adjusted by changing the current sense resistor R1. When measuring total system current, it may be necessary to include the supply current of the current monitor, which bypasses the current sense resistor, in the final result. This current can be measured and calibrated (together with the residual offset) by adjustment of the offset trim potentiometer, R2. This produces a deliberate offset that is temperature dependent. However, the supply current of the OP90 is also proportional to temperature and the two effects tend to track. Current in R4 and R5, which also bypasses R1, can be accounted for by a gain trim.
