The OPA1641AID is a single JFET-input ultralow distortion low-noise Operational Amplifier for use with broadcast studio equipment. The rail-to-rail output swing allows increased headroom, making this device 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. This device operates over a very wide supply voltage range of ±2.25 to ±18V. The operational amplifier is unity-gain stable and provide excellent dynamic behaviour over a wide range of load conditions.
