The OPA2209AIDR is a precision RRO Operational Amplifier achieves very low voltage noise density (2.2nV/√Hz) with a supply current of only 2.5mA (maximum). This amplifier 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 10V output swings. This excellent AC performance, combined with only 150μV (maximum) of offset and low drift over-temperature, makes the op-amp very suitable for fast, high-precision applications.
