AD8603/AD8607/AD8609 are single/dual/quad micro- power 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
The AD8603, AD8607, and AD8609 are precision micropower, low‑noise CMOS operational amplifiers with rail‑to‑rail input and output. They offer ultra‑low offset voltage (as low as 50 pV), low input bias current (1 pA max), and operate from 1.8 V to 5 V single‑supply or 0.9 V to 2.5 V dual‑supply, making them suitable for battery‑powered instrumentation, sensor interfaces, and low‑power ASIC applications.
These devices are offered in several small‑outline packages (5‑lead TSOT for AD8603, 8‑lead MSOP/SOIC for AD8607, and 14‑lead TSSOP/SOIC for AD8609). The datasheet includes detailed electrical characteristics, absolute maximum ratings, typical performance curves, supply current data, and an ordering guide with part numbers and package options.
| Offset Voltage (Vos) Max | 50 pV |
|---|---|
| Input Bias Current (Ib) Max | 1 pA |
| Supply Voltage Range (single‑supply) | 1.8 V to 5 V |
The maximum offset voltage is 50 pV.
They operate from 1.8 V to 5 V on a single supply or from 0.9 V to 2.5 V on a dual supply.
The AD8603 is available in a 5‑lead TSOT package (UJ‑5).
Yes, they are RoHS compliant parts.
