Description

The MAX4091AUK+ is a model of electronic component in the category of instrumentation op-amps. It is a versatile operational amplifier with excellent DC accuracy and Rail-to-Rail operation at the input and output. This component can operate with either a single supply voltage of 2.7V to 6V or split supplies of ±1.35V to ±3V. It has a low supply current requirement of less than 130µA, but is still capable of driving a 1kΩ load and has a low input-referred voltage noise of 12nV/√Hz. It also has the ability to drive loads in excess of 2000pF.
