Description for the OPA1641-Q1
The OPA1641-Q1 (single) and OPA1642-Q1 (dual) series are JFET-input, ultra-low distortion, low-noise operational amplifiers (op amps) fully specified for audio applications.
The rail-to-rail output swing allows increased headroom, making these devices ideal for use in any audio circuit. Features include 5.1-nV/√Hz noise, low total harmonic distortion + noise (THD+N) (0.00005%), a low input bias current of 2 pA, and low quiescent current of 1.8 mA per channel.
These devices operate over a very wide supply voltage range of ±2.25 V to ±18 V. The OPA164x-Q1 series of operational amplifiers are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions.
The dual version features completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.
