AD8657 18V, 22μA, 45NV/√HZ, Precision, RRIO, Quad Op Amp
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, respectively.
The AD8657/AD8659 operate from 2.7 V to 18 V supplies with a typical quiescent supply current of 18µA。 These devices use Analog Devices' patented DigiTrim® trim trim technology and have very low offset voltages. The AD8657/AD8659 also have high immunity to electromagnetic interference.
The AD8657/AD8659 feature low supply current, low offset voltage, very low input bias current, wide supply voltage range, and rail-to-rail inputs and outputs, making them ideal for current monitoring in process and motor control applications. In wireless/remote sensors/transmitters, the precision feature set of these devices is ideal for dc gain and buffering of sensor front-ends or high impedance input sources.
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 a 16-lead LFCSP package.
