OPA211AIDGKR

1.1nV /噪声，低功耗，采用微型DFN -8封装的高精度运算放大器 1.1nV/Noise, Low Power, Precision Operational Amplifier in Tiny DFN-8 Package

DESCRIPON

The OPA211 series achieves very low 1.1nV/√Hz noise density with a supply current of only 3.6mA. It also offers rail-to-rail output swing, which helps to maximize dynamic range. The OPA211 series’ extremely low voltage and current noise, high speed and wide output swing make it an excellent choice as a loop filter amplifier in PLL applications.
