GENERAL DESCRIPTION
The AD8613/AD8617/AD8619 are single, dual, and quad micropower, ra il-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.

Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
