OPA211 - Precision Operational Amplifier

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

  • 1 Low voltage noise: 1.1 nV/√Hz at 1 kHz.
  • 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:.
  • 80 MHz (G = 100).
  • 45 MHz (G = 1).
  • Slew rate: 27 V/μs.
  • 16-Bit settling: 700 ns.
  • Wide supp.
