... The precision of the AD707 makes tighter error budgets possible at a lower cost. 3. The low offset voltage drift and low noise of the AD707 allow the designer to amplify very small signals without sacrificing overall system performance. 4. The AD707 can be used where chopper amplifiers are required, but without the inherent noise and application problems ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD707 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... C @ – +125 C AD707 OP07 Although the initial offset voltage of the AD707 is very low nonetheless the major contributor to system error. In cases requiring additional accuracy, the circuit shown in Figure 19 can be used to null out the initial offset voltage. This method OP77 will also cancel the effects of input offset current error ...

... SETTLING TIME Figure 22 shows the AD707 settling to within its final value for output step in less than 100 s (in the test con- figuration shown in Figure 23). To achieve settling to 18 bits, any amplifier specified to have a gain would appear to be good enough, however, this is not the case ...

... AD707 PRECISION CURRENT TRANSMITTER The AD707’s excellent dc performance, especially the low offset voltage, low offset voltage drift and high CMRR, makes it possible to make a high precision voltage-controlled current transmitter using a variation of the Howland Current Source circuit (Figure 26). This circuit provides a bidirectional load current which is derived from a differential input voltage ...
