SOIC and Flatpack Pinout APPLICATIONS Downhole drilling and instrumentation Avionics Heavy industrial High temperature environments GENERAL DESCRIPTION The AD8634 is a single-supply, 10 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. This dual-channel op amp is offered in an 8-lead SOIC plastic 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 temperature...
