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.

1 For input differential voltages greater than 0.6 V, the input current should be
limited to less than 5 mA to prevent degradation or destruction of the input
devices.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL RESISTANCE
θJA is specified for the device soldered on a 4-layer JEDEC
standard printed circuit board (PCB) with zero airflow.
