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.
