AD8609AR GENERAL DESCRIPTION

The AD8603/AD8607/AD8609 are single/dual/quad micro-power rail-to-rail input and output amplifiers, respectively, thatfeature very low offset voltage as well as low input voltage andcurrent noise.These amplifiers use a patented trimming technique that achievessuperior precision without laser trimming. The parts are fullyspecified 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, lownoise, very low input bias currents, and low power consumptionmakes the AD8603/AD8607/AD8609 especially useful in portableand loop-powered instrumentation.The ability to swing rail to rail at both the input and outputenables designers to buffer CMOS ADCs, DACs, ASICs, andother wide output swing devices in low power, single-supplysystems.The AD8603 is available in a tiny 5-lead TSOT package. TheAD8607 is available in 8-lead MSOP and 8-lead SOIC packages.The AD8609 is available in 14-lead TSSOP and 14-lead SOICpackages.
