Max Voltage (typical range): 36 V
Min Voltage (typical range): 4.5 V
Description
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.
Key Features
