3 Description
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.
