The OPA1641 (single), OPA1642 (dual), and OPA1644 (quad) series are JFET-input, ultralow distorTIon, low-noise operaTIonal amplifiers fully specified for audio applicaTIons.

The OPA1641, OPA1642, and OPA1644 rail-to-rail output swing allows increased headroom, making these devices ideal for use in any audio circuit. Features include 5.1nV/√Hz noise, low THD+N (0.00005%), a low input bias current of 2pA, and low quiescent current of 1.8mA per channel.

These devices operate over a very wide supply voltage range of ±2.25V to ±18V. The OPA1641, OPA1642, and OPA1644 series of op amps are unity-gain stable and provide excellent dynamic behavior over a wide range of load condiTIons.
