MAX4039 - Maxim

MAX4039 Low IBIAS / +1.4V/800nA / Rail-to-Rail Op Amps with +1.2V Buffered Reference

The single MAX4036/MAX4037 and dual MAX4038/ MAX4039 operational amplifiers operate from a single +1.4V to +3.6V (without reference) or +1.8V to +3.6V (with reference) supply and consume only 800nA of supply current per amplifier, and 1.1µA for the optional reference. The MAX4036/MAX4038 feature a common-mode input voltage range from 0V to VDD - 0.4V at VDD .
