OPA1656 Datasheet (Texas Instruments) - Audio Operational Amplifier

OPA1656, Audio Operational Amplifier

The OPA1655 and OPA1656 (OPA165x) are BurrBrown™ op amps designed specifically for audio and industrial applications, where maintaining signal fidelity is crucial.

The FET-input architecture achieves a low 2.9‑nV/√Hz voltage noise density and 6‑fA/√Hz current noise density, allowing for very-low no
