ANALOG DEVICES AD706ARZ

AD706 is a dual channel, low power, bipolar opamp 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 increases by 5 at 125°C (unlike a JFET amp, for which IB doubles every 10°C for a 1000 increase at 125°C). It also achieves the microvolt offset voltage and low noise characteristics of a precision bipolar input amplifier. It is an excellent choice for use in low frequency active filters in 12-bit and 14-bit data acquisition systems, in precision instrumentation, and as a high quality integrator. It is widely used in application such as low frequency active filters, precision Instrumentation, precision Integrators.
