DESCRIPTION

The OPA604 is a 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 lownoise

FET input of the OPA604 provides wide dynamic

range, even with high source impedance. Offset voltage is

laser-trimmed to minimize the need for interstage coupling

capacitors.

The OPA604 is available in 8-pin plastic mini-DIP and SO-8

surface-mount packages, specified for the –25°C to +85°C

temperature range.
