GENERAL DESCRIPTION
The AD8657/AD8659 are dual and quad micropower, precision,
rail-to-rail input/output amplifiers optimized for low power and
wide operating supply voltage range applications.
The AD8657/AD8659 operate from 2.7 V to 18 V with a typical
quiescent supply current of 18 μA. The devices use the Analog
Devices, Inc., patented DigiTrim trimming technique, which
achieves low offset voltage. The AD8657/AD8659 also have
high immunity to electromagnetic interference.
The combination of low supply current, low offset voltage, very
low input bias current, wide supply range, and rail-to-rail input
and output make the AD8657/AD8659 ideal for current
monitoring in process and motor control applications. The
combination of precision specifications makes these devices
ideal for dc gain and buffering of sensor front ends or high
impedance input sources in wireless or remote sensors or
transmitters.
The AD8657/AD8659 are specified over the extended industrial
temperature range (40°C to +125°C). The AD8657 is available in
an 8-lead MSOP package and an 8-lead LFCSP package; the
AD8659 is available in a 14-lead SOIC package and 16-lead
LFCSP package.
