Remote/wireless sensors 60 Low power transimpedance amplifiers 50 GENERAL DESCRIPTION VSY = 2.7V VSY = 18V
The AD8657/AD8659 are dual and quad micropower, precision,
40 A) µ P (
rail-to-rail input/output amplifiers optimized for low power and
AM 30
wide operating supply voltage range applications.
R PE I SY
The AD8657/AD8659 operate from 2.7 V to 18 V with a typical
20
quiescent supply current of 18 μA. The devices use the Analog
10
Devices, Inc., patented DigiTrim® trimming technique, which achieves low offset voltage. The AD8657/AD8659 also have
0 –50 –25 0 25 50 75 100 125
023 high immunity to electromagnetic interference.

monitoring in process and motor control applications. The Single AD8538 OP196 combination of precision specifications makes these devices AD8603 ideal for dc gain and buffering of sensor front ends or high ADA4051-1 impedance input sources in wireless or remote sensors or Dual AD8539 AD8657 AD8622 transmitters. AD8607 ADA4091-2 The AD8657/AD8659 are specified over the extended industrial ADA4051-2 ADA4096-2 temperature range (−40°C to +125°C). The AD8657 is available in Quad AD8609 AD8659 AD8624 an 8-lead MSOP package and an 8-lead LFCSP package; the ADA4091-4 AD8659 is available in a 14-lead SOIC package and 16-lead ADA4096-4 LFCSP package.
