GENERAL DESCRIPTION
The AD8613/AD8617/AD8619 are single, dual, and quad
micropower, rail-to-rail input and output amplifiers that feature
low supply current, low input voltage, and low current noise.
The parts are fully specified to operate from 1.8 V to 5.0 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
and 8-lead SOIC packages. The AD8619 is available in 14-lead
TSSOP and 14-lead SOIC packages.
