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.
