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.
