Texas Instruments  OPA1642AQDGKRQ1

The OPA1641-Q1 (single) and OPA1642-Q1 (dual) series are JFET-input, ultra-lowdistortion, low-noise operational amplifiers (op amps) fully specified for audioapplications.

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

These devices operate over a very wide supply voltage range of ±2.25 V to ±18 V. TheOPA164x-Q1 series of operational amplifiers are unity-gain stable and provide excellent dynamicbehavior over a wide range of load conditions.

The dual version features completely independent circuitry for lowest crosstalk andfreedom from interactions between channels, even when overdriven or overloaded.
