Description

The OPA211 series of precision operational amplifiers achieves very low 1.1nV/√Hz noisedensity 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 these devices an excellent choice as a loop filter amplifier in PLL applications.

In precision data acquisition applications, the OPA211 series of op amps 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).

The OPA211 series is specified over a wide dual-power supply range of ±2.25V to ±18V, or for single-supply operation from +4.5V to +36V.

The OPA211 is available in the small DFN-8 (3mm × 3mm), MSOP-8, and SO-8 packages. A dual version, the OPA2211, is available in the DFN-8 (3mm × 3mm) or an SO-8 PowerPAD™ package. This series of op amps is specified from TA = -40°C to +125°C.
