The OPA1656 is a Burr-Brown operational amplifier(op amp) 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 OPA1656 delivers a low distortion of 0.000035% (-129 dB) at 20 kHz, and improves audio signal fidelity across the full audio bandwidth. This device also features excellent output current drive capability, offering rail-to-rail output swing to within 250 mV of the power supplies with a 2-k load, and can deliver 100 mA of output current.
