OPA404
Quad High-Speed Precision
Difet ® OPERATIONAL AMPLIFIER
FEATURES
q WIDE BANDWIDTH: 6.4MHz
q HIGH SLEW RATE: 35V/µs
q LOW OFFSET: ±750µV max
q LOW BIAS CURRENT: ±4pA max
q LOW SETTLING: 1.5µs to 0.01%
q STANDARD QUAD PINOUT
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.
APPLICATIONS
