OPA211-HT Datasheet Precision Operational Amplifier

Manufacturer: Texas Instruments

Overview: OPA211-HT www.ti.com SBOS481D – JULY 2009 – REVISED OCTOBER 2013 1.

General Description

The OPA211 series of precision operational amplifiers achieves very low 1.1 nV/√Hz noise density with a supply current of only 3.6 mA.

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.
