Product Introduction
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 a patented 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.
