Product Introduction

The OPA211 high-precision operational amplifier of this series achieves a very low 1.1nV/ Hz noise density is only 3.6 mA with a supply current. The series also offers rail-to-rail output swing, where the largest dynamic range is available.

The extremely low voltage and low current noise, high speed, and wide output swing of the OPA211 series make these devices ideal for cyclic phase-locked loop filter amplifier applications.

In precision data acquisition applications, the OPA211 series of op amps offers a 700ns settling time with 16-bit accuracy over the entire 10V output swing. This AC performance, with only 125μV offset and 0.35μV combine/temperature drift exceeding °C, makes driving high-precision 16-bit analog-to-digital converters (ADCs) or buffered high-resolution output OPA211s digital-to-analog converters (DACs).
