Product Summary
The AD704JN is a quad, low power bipolar op amp that has the low input bias current of a BiFET amplifier but which offers asignificantly lower IB drift over temperature. The AD704JN utilizes Super-beta bipolar input transistors to achieve picoampere input biascurrent levels (similar to FET input amplifiers at room tempera-ture), while its IB typically only increases by 5× at +125°C(unlike a BiFET amp, for which IB doubles every 10°C resultingin a 1000× increase at +125°C) . Furthermore the AD704JN achieves 75μV offset voltage and low noise characteristics of aprecision bipolar input op amp. Applications of the AD704JN include: Industrial/Process Controls, Weigh Scales, ECG/EKG Instrumentation, Low Frequency Active Filters.
