Picoampere输入电流双极四路运算放大器 Picoampere Input Current Quad Bipolar Op Amp
PRODUCT DESCRIPTION
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 at +125°C. Furthermore the AD704 achieves 75 µV offset voltage and low noise characteristics of a precision bipolar input op amp.
