The OPA2604 is a dual, FET-input operational amplifier designed for enhanced AC performance. Low distortion, low noise, and wide bandwidth provide superior performance in high quality audio and other applications requiring dynamic performance.
New circuit techniques and special laser-trimming of dynamic circuit performance yield low harmonic distortion. The result is an operational amplifier 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 8-pin plastic mini-DIP and 8-Pin SOIC surface-mount packages, specified for the –25°C to 85°C temperature range.
