GENERAL DESCRIPTION

The OP400 is the first monolithic quad operational amplifier that features OP77-type performance. Precision performance is not sacrificed with the OP400 to obtain the space and cost savings offered by quad amplifiers.

FEATURES

Low input offset voltage: 150 μV maximum

Low offset voltage drift over –55°C to +125°C: 1.2 pV/°C maximum

Low supply current (per amplifier): 725 μA maximum

High open-loop gain: 5000 V/mV minimum

Input bias current: 3 nA maximum

Low noise voltage density: 11 nV/√Hz at 1 kHz

Stable with large capacitive loads: 10 nF typical

Pin-compatible to LM148, HA4741, RM4156, and LT1014, with improved performance

Available in die form
