OPA2211 Overview
The OPAx211 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 OPAx211 series make these devices an excellent choice as a loop filter amplifier in PLL applications.
