GENERAL 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
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 supply
current of 6.5 mA with excellent ac characteristics under all
supply conditions, makes the AD825 well-suited for many
demanding applications.
