DESCRIPTION
The OPA404 is a high performance monolithic
Difet ^®(dielectrically-isolated FET) quad operational
amplifier. It offers an unusual combination of very-
low bias current together with wide bandwidth and
fast slew rate.
Noise, bias current, voltage offset, drift, and speed are
superior to BIFET^® amplifiers.
Laser-trimming of thin-film resistors gives very low
offset and drift—the best available in a quad FET op
amp.
The OPA404's input cascode design allows high pre-
cision input specifications and uncompromised high-
speed performance.
Standard quad op amp pin configuration allows up-
grading of existing designs to higher performance
levels. The OPA404 is unity-gain stable.
