双路FET输入，低失真运算放大器 DUAL FET-INPUT, LOW DISTORTION OPERATIONAL AMPLIFIER
description
The OPA2604 is a dual, FET-input operational amplifier designed for enhanced AC performance. Very low distortion, low noise and wide bandwidth provide superior performance in high quality audio and other applications requiring excellent dynamic performance.
New circuit techniques and special laser trimming of dynamic circuit performance yield very low harmonic distortion. The result is an op amp with exceptional sound quality. The low-noise FET input of the OPA2604 provides wide dynamic range, even with high source impedance. Offset voltage is laser-trimmed to minimize the need for interstage coupling capacitors.
The OPA2604 is available in a SO-8 surface-mount package, specified for the −40°C to +85°C temperature range.
