Product Summary
The AD704TQ 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. Furthermore the AD704TQ achieves 75mV offset voltage and low noise characteristics of a precision bipolar input op amp. The applications of it include: (1)Industrial/Process Controls; (2)Weigh Scales; (3)ECG/EKG Instrumentation; (4)Low Frequency Active Filters.
