The AD825 is a superbly optimized operational amplifier for high speed, low cost, and dc parameters, making it ideally
10V 200ns
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
10V
MUX outputs, creating minimal offset and gain errors. 00876-E-003 The AD825 is ful y specified for operation with dual ±5 V and Figure 3. Performance with Rail-to-Rail Input Signals ±15 V supplies. This power supply flexibility, and the low supply current of 6.5 mA with excel ent ac characteristics under all supply conditions, makes the AD825 wel -suited for many demanding applications.
