OPA1678IDGKT-Low Distortion, Low Noise, General Purpose Audio Op Amp

The OPA1678 (dual-channel) and OPA1679 (quad-channel) operational amplifiers offer higher system-level 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 fidelity. They also offer rail-to-rail output swing to within 800 mV with a 2-kΩ load, which increases headroom and maximizes dynamic range.

The OPA1678 and OPA1679 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 to accommodate the power supply constraints of many types of audio products. These op amps are unity-gain stable and have excellent dynamic behavior over a wide range of load conditions allowing them to be used in many audio circuits.

The OPA167x amplifiers use completely independent internal circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.

The OPA167x temperature ranges are specified from –40°C to +85°C.
