GENERAL DESCRIPTION
The AD8613/AD8617/AD8619 are single, dual, and quad micro-
power, rail-to-rail input and output amplifiers that feature low
supply current, as well as low input voltage and current noise.

The parts are fully specified to operate from 1.8 V to 5 V single
supply, or 0.9 V and 2.5 V dual supply. The combination of low
noise, very low input bias currents, and low power consumption
make the AD8613/AD8617/AD8619 especially useful in portable
and loop-powered instrumentation.

The ability to swing rail-to-rail at both the input and output
enables designers to buffer CMOS ADCs, DACs, ASICs, and
other wide output swing devices in low power, single-supply
systems.
