Product Introduction

The OPA1641 (single), OPA1642 (dual) and OPA1644 (quad) series are JFET input, ultra-low distortion, and low-noise operational amplifiers specified for full audio applications.

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

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