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.
The AD8613 is available in a 5-lead SC70 package and a 5-lead
TSOT-23 package. The AD8617 is available in 8-lead MSOP,
8-lead SOIC, and 8-lead LFCSP packages. The AD8619 is
available in 14-lead TSSOP and 14-lead SOIC packages. The
AD8617W is qualified for automotive applications and is
available in 8-lead MSOP and 8-lead SOIC packages. The
AD8619W is qualified for automotive applications and is
available in 14-lead SOIC and 14-lead TSSOP packages.
