General Description

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 1.1?A for the optional reference. The MAX4036/MAX4038 feature a common-mode input voltage range from 0V to VDD - 0.4V at VDD = 1.4V. The MAX4037/MAX4039 feature a 1.232V voltage reference capable of sourcing 100?A and sinking 20?A.
