OPA1679IPWR Product Details

OPA1679IPWR Description


The quad-channel OPA1679IPWR op-amp offers higher system-level performance over legacy op-amps commonly used in audio circuitry.

The OPA1679IPWR amplifier achieves a low 4.5-nV/√Hz noise density and low distortion of 0.0001% at 1 kHz, which improves audio signal fidelity. This op-amp OPA1679IPWR also offers rail-to-rail output swing to within 800 mV with a 2-kΩ load, which increases headroom and maximizes dynamic range.



OPA1679IPWR Features


  • Low noise: 4.5 nV/√Hz at 1 kHz

  • Low distortion: 0.0001% at 1 kHz

  • High open-loop gain: 114 dB

  • High common-mode rejection: 110 dB

  • Low quiescent current:

  •   – 2 mA per channel

  • Low input bias current: 10 pA (typical)



OPA1679IPWR Applications


  • Professional microphones and wireless systems

  • Professional audio mixer/control surface

  • Guitar amplifier and other music instrument amplifier

  • A/V receiver

  • Automotive external amplifier
