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
