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, makes the AD825 well suited for many

demanding applications.
