AD8607

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.
