GENERAL DESCRIPTION
The AD8603/AD8607/AD8609 are single/dual/quad micropower rail-to-rail input and output amplifiers, respectively, that feature 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 8-lead SOIC packages. The AD8609 is available in 14-lead TSSOP and 14-lead SOIC packages.
