The AD8657 is an 18V precision micropower CMOS RRIO operational amplifier with features such as micropower at high voltage, low offset voltage, single-supply and dual-supply operation, low input bias current, and gain bandwidth.
The AD8657 is a dual, micropower, precision rail‑to‑rail input/output amplifier optimized for low power and a wide supply voltage range. It operates from 2.7 V up to 18 V and features a typical quiescent supply current of 18 µA, 350 pV maximum offset voltage, and 20 pA low input bias current.
Designed for portable systems, current monitors, loop drivers, sensor front‑ends and wireless applications, the device is offered in 8‑lead MSOP and 8‑lead LFCSP packages and is rated for –40 °C to +125 °C operation.
