Description
General part information
OPA1677 Series
The single-channel OPA1677, dual-channel OPA1678, and quad-channel OPA1679 (OPA167x) op amps offer higher system-level performance over legacy op amps commonly used in audio circuitry.
The OPA167x amplifiers achieve a low 4.5-nV/√Hznoise density and low distortion of 0.0001% at 1 kHz, which improves audio signal fidelity. These devices also offer rail-to-rail output swing to within 800 mV with a 2-kΩ load, which increases headroom and maximizes dynamic range.
To accommodate the power-supply constraints of many types of audio products, the OPA167x operate over a very-wide supply range of ±2.25 V to ±18 V (or 4.5 V to 36 V) on only 2 mA of supply current. These op amps are unity-gain stable and have excellent dynamic behavior over a wide range of load conditions, allowing the OPA167x to be used in many audio circuits.
