应用功能：Dual Picoampere InputCurrent Bipolar Op Amp The AD706 is a dual, low power, bipolar op amp that has thelow input bias current of a BiFET amplifier but which offersasignificantlylowerIBdriftovertemperature. It utilizes superbetabipolar input transistors to achieve picoampere input bias currentlevels (similar to FET input amplifiers at room temperature),while its IB typically only increases by 5´ at 125°C (unlikea BiFET amp, for which IB doubles every 10Cfora1000increase at 125°C).
