The AD8634 is a precision, 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 from ±1.5 V to ±15 V) and at very high temperatures.The AD8634 is well suited for applications that require both ac and dc precision 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.This dual-channel op amp is offered in an 8-lead SOIC package with an operating temperature range of −40°C to +175°C. It is also available in an 8-lead ceramic flat package (FLATPACK) with an operating temperature range of −40°C to +210°C. Both packages are designed for robustness at extreme temperatures and are qualified for up to 1000 hours of operation at the maximum temperature rating.The AD8634 is a member of a growing series of high temperature qualified products offered by Analog Devices, Inc.
