GENERAL DESCRIPTION
The AD8603/AD8607/AD8609 are, single/dual/quad micro-
power rail-to-rail input and output amplifiers, respectively, that
features very low offset voltage as well as low input voltage and
current noise.
These amplifiers use a patented trimming technique that
achieves superior precision without laser trimming. The parts
are fully specified to operate from 1.8 V to 5.0 V single supply
or from ±0.9 V to ±2.5 V dual supply. The combination of low
offsets, low noise, very low input bias currents, and low power
consumption make the AD8603/AD8607/AD8609 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 AD8603 is available in a tiny 5-lead TSOT-23 package. The
AD8607 is available in 8-lead MSOP and SOIC packages. The
AD8609 is available in 14-lead TSSOP and SOIC packages.
