OPA2211AIDRGT Datasheet PDF - TI

The OPA2211AIDRGT is a low power precision Operational Amplifier for use with active filters. The operational amplifier achieves very low 1.1nV/√Hz noise density with a supply current of only 3.6mA. This series also offers rail-to-rail output swing, which maximizes dynamic range. The extremely low voltage and low current noise, high-speed and wide output swing of the OPA211 series make this device an excellent choice as a loop filter amplifier in PLL applications. In precision data acquisition applications, the OPA211 series of operational amplifiers provides 700ns settling time to 16-bit accuracy throughout 10V output swings. This AC performance, combined with only 125µV of offset and 0.35µV/°C of drift over temperature, makes the OPA211 ideal for driving high-precision 16-bit analog-to-digital converters (ADCs) or buffering the output of high-resolution digital-to-analog converters (DACs).
