Introduction

AI Translation

The OPA1641-Q1 (single-channel) and OPA1642-Q1 (dual-channel) series both belong to JFET-input, ultra-low distortion, low-noise operational amplifiers and are fully suitable for audio designs. The rail-to-rail output swing can increase the margin, making these devices highly suitable for use in any audio circuit. Features include: 5.1 nV/√Hz noise, low total harmonic distortion + noise (THD+N) (0.00005%), 2 pA low input bias current, and a low quiescent current of 1.8 mA per channel. These devices can operate over a very wide power supply voltage range from ±2.25 V to ±18 V. The OPA164x-Q1 series operational amplifiers have stable unity gain and can provide excellent dynamic behavior under various load conditions. The dual-channel version has fully independent circuits, which can minimize crosstalk and is not affected by the interaction between channels even during overdrive or overload.
