35 04 The AD8603/AD8607/AD8609 are single/dual/quad micro- Figure 3. 8-Lead SOIC (R Suffix) power rail-to-rail input and output amplifiers, respectively, that feature very low offset voltage as well as low input voltage and

current noise.
–IN A 2 13 –IN D
These amplifiers use a patented trimming technique that achieves
