DESCRIPTION
The OPA404 is a high performance monolithic
Difet ®(dielectrically-isolated FET) quad operational
amplifier. It offers an unusual combination of verylow
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 precision
input specifications and uncompromised highspeed
performance.
Standard quad op amp pin configuration allows upgrading
of existing designs to higher performance
levels. The OPA404 is unity-gain stable.
