OPA1656 amplifier equivalent, audio operational amplifier.
* Ultra-low noise:
– Voltage noise: 2.9 nV/√Hz at 10 kHz
– Current noise: 6 fA/√Hz at 1 kHz
* Low distortion:
– 0..
* Professional microphones and wireless systems
* Professional audio mixer/control surface
* Guitar amplifie.
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/√.
