GENERAL DESCRIPTIONThe AD8631 brings precision and bandwidth to the SOT-23-5
package at single supply voltages as low as 1.8 V and low supply
current. The small package makes it possible to place the AD8631
next to sensors, reducing external noise pickup.
The AD8631 and AD8632 are rail-to-rail input and output bipolar
amplifiers with a gain bandwidth of 4 MHz and typical voltage
offset of 0.8 mV from a 1.8 V supply. The low supply current and
the low supply voltage makes these parts ideal for battery-powered
applications. The 3 V/µs slew rate makes the AD8631/AD8632 a
good match for driving ASIC inputs, such as voice codecs.
The AD8631/AD8632 is specified over the extended industrial
(–40�C to +125�C) temperature range. The AD8631 single is
available in 5-lead SOT-23 surface-mount packages. The dual
AD8632 is available in 8-lead SOIC and µSOIC packages.

NOTESStresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.For supply voltages less than 6 V the input voltage is limited to the supply voltage.
NOTEθJA is specified for worst-case conditions, i.e., θJA is specified for device soldered
in circuit board for SOT-23 and SOIC packages.

CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD8631/AD8632 features proprietary ESD protection circuitry, permanent dam-
age may occur on devices subjected to high energy electrostatic discharges. Therefore, proper
ESD precautions are recommended to avoid performance degradation or loss of functionality.
