DESCRIPTION

The OPA2604 is a dual, FET-input operational ampli-

fier 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 8-pin plastic mini-DIP

and SO-8 surface-mount packages, specified for the

–25

°C to +85°C temperature range.
