Product Summary

The AD704J 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 Superbeta 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℃ (unlike a BiFET amp, for which IB doubles every 10℃ resulting in a 1000x increase at +125℃). Furthermore the AD704J achieves 75 mV offset voltage and low noise characteristics of a precision bipolar input op amp. The applications of the AD704J include Industrial/Process Controls, Weigh Scales, ECG/EKG Instrumentation, Low Frequency Active Filters.
