This series also offers rail-to-rail output swing, which helps to maximize dynamic range. In precision data acquisition applications, the OPA209 provides fast settling time to 16-bit accuracy, even for 10-V output swings. This excellent ac performance, combined with only 150 µV (maximum) of offset and low drift over temperatu...
