GENERAL DESCRIPTION

The AD8634 is a single-supply, 9.7 MHz bandwidth, dual amplifier that features rail-to-rail outputs. The AD8634 is guaranteed to operate from 3 V to 30 V (or ±1.5 V to ±15 V) and at very high temperatures.

The AD8634 is well suited for single-supply applications that require both ac and precision dc performance. The combination of wide bandwidth, low noise, and precision makes the AD8634 useful in a wide variety of applications, including filters and interfacing with a variety of sensors.
