Texas Instruments OPA1656
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 noise performance in a wide variety of circuits. The high bandwidth and high open-loop-gain design of the OPA165x delivers a low distortion of 0.000035% (–129 dB) at 20 kHz, and improves audio signal fidelity across the full audio bandwidth.| Part No. | OPA1656 |
