DESCRIPTION
The OPA211 series achieves very low 1.1nV/√Hz noise density with a supply current of only 3.6mA. It also offers rail-to-rail output swing, which helps to maximize dynamic range. The OPA211 series’ extremely low voltage and current noise, high speed and wide output swing make it an excellent choice as a loop filter amplifier in PLL applications. In precision data acquisition applications, the OPA211 series of op amps provide <1µs settling time to 16-bit accuracy even for 10V output swings. This ac performance, combined with only 100µV of offset and low drift over temperature, make the OPA211 highly suitable for driving fast, high-precision analog-to-digital converters (ADCs) or buffering the outputs of high-resolution digital-to-analog converters (DACs). The OPA211 is specifie...
