DESCRIPTION
(7)
V+
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 dy-
namic 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 OPA604 provides wide dynamic
range, even with high source impedance. Offset voltage is
laser-trimmed to minimize the need for interstage coupling
capacitors.
