5962-8777101M3A vs OP400ATCMDA vs AD704SE/883B Comparison

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

PRODUCT DESCRIPTION The AD704 is a quad, low power bipolar op amp that has the low input bias current of a BiFET amplifier but which offers a significantly lower IB drift over temperature. It utilizes Super beta bipolar input transistors to achieve picoampere input bias current levels (similar to FET input amplifiers at room temperature), while its IB typically only increases by 5× at +125°C (unlike a BiFET amp, for which IB doubles every 10°C resulting in a 1000× increase at +125°C). Furthermore the AD704 achieves 75 µV offset voltage and low noise characteristics of a precision bipolar input op amp.
