CAUTION
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 AD515A 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.
Open Loop Gain is specified with or without pulling of V
A conservative design would not exceed 750 pF of load capacitance.
Input Offset Voltage specifications are guaranteed after 5 minutes of
Bias Current specifications are guaranteed after 5 minutes of operation at

Specifications shown in boldface are tested on all production units at final test.
Specifications subject to change without notice.
1f it is possible for the input voltage to exceed the supply voltage, a series
protection resistor should be added to limit input current to 0.1 mA.
The input devices can handle overload currents of 0.1 mA indefinitely without
damage. See next page.
