1nV/√Hz noise density 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 1...
