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.
