TEXAS INSTRUMENTS OPA2211AIDDA

The OPA2211AIDDA is a low power precision Operational Amplifier achieves very low 1.1nV/√Hz noise density with a supply current of only 3.6mA. This amplifier 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 op-amp made an excellent choice as a loop filter amplifier in PLL applications. In precision data acquisition applications, the OPA211 series of the op-amp 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 op-amp ideal for driving high-precision 16-bit analogue-to-digital converters (ADCs) or buffering the output of high-resolution digital-to-analogue converters (DACs).
