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 temperatures
and are qualified for 1000 hours of operation at the maximum
temperature rating.
