PRODUCT DESCRIPTION
The AD825 is a superbly optimized operational amplifier for
high speed, low cost, and dc parameters, making it ideally suited
for a broad range of signal conditioning and data acquisition
applications. The ac performance, gain, bandwidth, slew rate
and drive capability are all very stable over temperature. The
AD825 also maintains stable gain under varying load conditions.
The unique input stage has ultralow input bias current and
ultralow input current noise. Signals that go to either rail on
this high performance input do not cause phase reversals at the
output. These features make the AD825 a good choice as a buffer
for MUX outputs, creating minimal offset and gain errors.
The AD825 is fully specified for operation with dual ±5 V and
±15 V supplies. This power supply flexibility, and the low sup-
ply current of 6.5 mA with excellent ac characteristics under
all supply conditions, make the AD825 well suited for many
demanding applications.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD825 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.
