OPA2211 - Precision Operational Amplifier

Download the OPA2211 datasheet PDF. This datasheet also covers the OPA211 variant, as both devices belong to the same precision operational amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key Features

  • Input voltage noise: 80 nVPP (0.1 to 10 Hz).
  • THD + N:.
  • 136 dB (G = 1, ƒ = 1 kHz).
  • Offset voltage: 125 μV (maximum).
  • Offset voltage drift: 0.35 μV/°C (typical).
  • Low supply current: 3.6 mA/Ch (typical).
  • Unity-gain stable.
  • Gain bandwidth product:.
