Product Summary
The AD706AQ is a dual, low power, bipolar op amp that has the low input bias current of a JFET 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 JFET amp, for which IB doubles every 10℃ for a 1000× increase at 125℃). The AD706AQ also achieves the microvolt offset voltage and low noise characteristics of a precision bipolar input amplifier. The applications of the AD706AQ include Low Frequency Active Filters, Precision Instrumentation, and Precision Integrators.
