Product introduction

This series of high precision operational amplifiers OPA211 achieves very low 1.1nV / HzThe noise density is only 3.6 mA with one supply current. The series also offers rail-to-rail output swings with maximum dynamic range.

Very low voltage and low current noise, high speed, and the OPA211's wide output swing make these devices ideal for use as a cyclic phase-locked loop filter amplifier application.

In precision data acquisition applications, the OPA211 family of op amps provides 700ns settling time with 16-bit accuracy over the full 10V output swing. This ac performance, with only 125μV offset and 0.35μV combined/drifted over °C, makes it ideal for driving a high-precision 16-bit analog-to-digital converter (ADC) or buffered high-resolution output of the OPA211 digital-to-analog converter (DAC).
