OPA2211-EP - Precision Operational Amplifier

General Description

The OPA2211-EP 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: 180 μV (Max).
  • Offset Voltage Drift: 0.35 μV/°C (Typ).
  • Low Supply Current: 3.6 mA/Ch (Typ).
  • 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 Supply Range: ±2.25 V to ±18 V, +4.5 V.
