www.addmtek.com DESCRIPTION The AMC2244/AMC2344/AMC2444 are dual, triple and quad versions of the high speed, low power, and low cost monolithic operational amplifiers. These devices consume only 7mA of supply current per amplifier to achieve the performance of unity gain stable, 270V/s slew rate and 60 MHz gain- bandwidth product. The power supply operating range is from 18V down to as low as 2V. For single-supply operation, the AMC2244/AMC2344/AMC2444 operate from 36V down to 2.5V.

AMC2244/AMC2344/AMC2444
APPLICATION INFORMATION Product Description The AMC2244/AMC2344/AMC2444 are low-power wideband monolithic operational amplifiers implemented with a classical voltage-feedback topology. This allows them to be used in a variety of applications where current-feedback amplifiers are not appropriate. For example, a capacitor to be placed in the feedback path, making it an excellent choice for applications such as active filters, sample-and-holds, or integrators. Similarly, because of the ability to use diodes in the feedback network, the AMC2244/AMC2344/AMC2444 are an excellent choice for applications such as fast log amplifiers. Power Dissipation In order to prevent the junction temperature to exceed 150C , it is important to calculate the maximum junction temperature (TJmax) for all applications to determine if power-supply voltages, load conditions, or package type need to be modified such that the AMC2244/AMC2344/AMC2444 remain in the safe operating area. These parameters are related as follows: TJmax = Tmax + (JAx PDmaxtotal) Where PDmaxtotal is the sum of the maximum power dissipation of each amplifier in the package (PDmax). PDmax for each amplifier can be calculated as follows : PDmax= ( 2 x VS x ISmax + (VS - Voutmax) x ( Voutmax /RL)) where: Tmax =Maximum Ambient Temperature JA = Thermal Resistance of the Package PDmax = Maximum Power Dissipation of 1 Amplifier VS = Supply Voltage ISmax = Maximum Supply Current of 1 Amplifier Voutmax = Maximum Output Voltage Swing of the Application RL = Load Resistance To serve as a guide for the user, we can calculate maximum allowable supply voltages for the example of the video cable-driver below since we know that TJmax = 150C, Tmax = 75C, ISmax = 8.2 mA, and the package JAs are shown in Table 1. If we assume (for this example ) that we are driving a back-terminated video cable, then the maximum average value (over duty-cycle) of Voutmax is 1.4V, and RL = 150, giving the results seen in Table 1.

AMC2244/AMC2344/AMC2444
APPLICATION INFORMATION (CONTD.) Single Supply Operation The AMC2244/AMC2344/AMC2444 have been designed to operate over a wide input and output voltage range. However, the AMC2244/AMC2344/AMC2444 are also suitable for single-supply operation. With a 5V supply and RL = 500, the output voltage swing is from 200mV to 3.9V, this results in a 3.7V output swing on a single 5V supply. The single supply operation range is from as high as 36V to 2.5V. For a single 2.5V supply application, the output swing can still have 1VPP. Gain-Bandwidth Product and the-3 dB Bandwidth The gain-bandwidth product of AMC2244/AMC2344/AMC2444 is 60 MHz while using only 7mA of supply current per amplifier. For gains greater than 4, their closed-loop -3 dB bandwidth is approximately equal to the gain-bandwidth product divided by the noise gain of the circuit. For gains less than 4, higher-order poles in the amplifiers' transfer function contribute to even higher closed loop bandwidths. For example, the -3 dB bandwidth is 120 MHz at a gain of + 1, dropping to 60 MHz at a gain of +2. Output Drive Capability The AMC2244/AMC2344/AMC2444 have been designed to drive low impedance loads. The output swing can easily reach 6VPP into a 150 load. This features the AMC2244/AMC2344/AMC2444 in the field of RF, IF and video applications. Furthermore, even at low temperatures, the current drive still remains a minimum of 35mA. For signal transmission and distribution, a back-terminated cable (75 in series at the drive end, and 75 to ground at the receiving end) is preferred since the impedance match at both ends will absorb any reflections. However, when double termination is used, the received signal is halved; therefore a gain of 2 configuration is typically used to compensate for the attenuation. Capacitive Loads While driving the capacitive loads, the AMC2244/AMC2344/AMC2444 remain stable by automatically reducing their gain-bandwidth product as capacitive load increases. Therefore, for maximum bandwidth, capacitive loads should be reduced as much as possible or isolated via a series output resistor (RS). Similarly, coax lines can be driven, but best AC performance is obtained when they are terminated with their characteristic impedance so that the capacitance of the coaxial cable will not add to the capacitive load seen by the amplifier. Although stable with all capacitive loads, some peaking still occurs as load capacitance increases. A series resistor at the output can be used to reduce this peaking and further improve stability. Printed-Circuit Layout In most applications, good PCB layout is necessary for optimum performance. Ground-plane construction is highly recommended for good power supply bypassing. A 0.1 F ceramic capacitor is recommended for bypassing both supplies. Lead lengths should be as short as possible, and bypass capacitors should be placed as close to the device pins as possible. For good AC performance, parasitic capacitances should be kept to a minimum at both inputs and at the output. Resistor values should be dept under 5 Kbecause of the RC time constants associated with the parasitic capacitance. Metal-film and carbon resistors are both acceptable, use of wire-wound resistors is not recommended because of their parasitic inductance. Similarly, capacitors should be low-inductance foe best performance.
