OPA1678 - Low-Distortion Audio Operational Amplifiers
The OPA1678 (dual-channel) and OPA1679 (quadchannel) operational amplifiers offer higher systemlevel performance over legacy op amps commonly used in audio circuitry.
The OPA167x amplifiers achieve a low 4.5-nV/√Hz noise density and low distortion of 0.0001% at 1 kHz, which improves audio signal fid
