Analog Devices AD704 Manuals

This document describes the detailed requirements for the Quad Picoampere Input Current, Precision, Bipolar Op Amp AD704/883B Rev. C. The product features low input current, low offset voltage, and other characteristics.

The document introduces the characteristics of the AD704 product, including high precision, low offset voltage, low offset voltage drift, low input bias current, low noise and low power consumption.

The AD704 is a quad, low power bipolar op amp that has the low input bias current of a BiFET amplifier and offers a significantly lower IB drift over temperature. It uses superbeta bipolar input transistors to achieve picoampere input bias current levels (similar to FET input amplifiers at room temperature), while its IB typically increases only by 5× at 125°C. The op amp is suitable for applications such as industrial/process controls, weigh scales, ECG/EKG instrumentation, and low frequency active filters.

The AD704 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 super-beta 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°C (unlike a BiFET amp, for which IB doubles every 10°C resulting in a 1000× increase)
