OPA1655DR General Purpose Amplifier 1 Circuit Rail-to-Rail SO8

The OPA1655 are 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. These devices also feature excellent output current drive capability, offering rail-to-rail output swing to within 250 mV of the power supplies with a 2‑kΩ load, and can deliver 100 mA of output current.
