AD8609ARZ-REEL7

The AD8603/AD8607/AD8609 are single/dual/quad, micropower, rail-to-rail input and output amplifiers featuring ultralow offset voltage, low input voltage noise, and low current noise. These amplifiers employ a patented trimming technique that achieves excellent accuracy without laser trimming. All three devices operate from a 1.8 V to 5.0 V single supply or ±0.9 V to ±2.5 V dual supplies. The combination of low offset, low noise, ultralow input bias current, and low power consumption makes the AD8603/AD8607/AD8609 ideally suited for portable and loop-powered instrumentation applications. Rail-to-rail swing capability at both input and output enables designers to buffer CMOS ADCs, DACs, ASICs, and other wide output swing devices in low power, single-supply systems.
