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.
