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
makes 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 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. 6 –IN B …
