Description

The dual OPA1662 and quad OPA1664 (OPA166x) series of bipolar-input SoundPlus™ audio operational amplifiers achieve a low 3.3nV/√Hz noise density with an ultra-low distortion of 0.00006% at 1kHz.

Features

  • Low noise: 3.3nV/√Hz at 1kHz.
  • Low distortion: 0.00006% at 1kHz.
  • Low quiescent current: 1.5mA per channel.
  • Slew rate: 17V/μs.
  • Wide gain bandwidth: 22MHz (G = +1).
  • Unity gain stable.
  • Rail-to-rail output.
  • Wide supply range: ±1.5V to ±18V or 3V to 36V.
  • Dual and quad versions available.
  • Small package sizes: Dual: SOIC-8 and VSSOP-8 Quad: SOIC-14 and TSSOP-14 2.
