Audio operational amplifier (op-amps)
Texas Instruments Semiconductor
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.
