AD8657

The AD8657 is specified over the extended industrial temperature range (-40°C to +125°C)and available in 8-lead MSOP and 8-lead 3x3x0.75 LFCSP packages. The AD8657 operates from 2.7V up to 18 V with a quiescent supply current of 20 uA. The combination of low supply current, low offset voltage, very low input bias current, wide supply range and rail-to-rail inputs and output make the AD8657 ideal for current monitoring and current loops in process and motor control. The AD8657 is a dual, micropower, precision, rail-to-rail input/output amplifier optimized for low power and wide operating supply voltage range applications. The combination of precision specifications makes this devices ideal l for DC gain and buffering of sensor front-ends or high impedance input sources in wireless or remote sensors or transmitters.

The features of AD8657 can be summarized as (1)micropower at high voltage (18V): 20 A typ; (2)gain bandwidth: 200 kHz; (3)offset voltage: 300 V; (4)single-supply operation: 2.7 to 18 Volts; (5)dual-supply operation: +/-1.35 to +/-9 Volts; (6)output drive: 10 mA; (7)unity gain stable.

The absolute maximum ratings of AD8657 are (1)supply voltage: TBD; (2)input voltage: TBD; (3)input current: TBD; (4)differential input voltage: 2 ±V SY; (5)output short-circuit duration to gnd: indefinite; (6)storage temperature range: -65°C to +150°C; (7)operating temperature range: -40°C to +125°C; (8)junction temperature range: -65°C to +150°C; (9)lead temperature (Soldering, 60 sec): 300°C.
