Non-Inverting Level Shifter Requires Only One Op Amp, One Supply Voltage.

The article offers information on the use of non-inverting level shifter in a single-supply voltage while preserving signal polarity. The circuit copes all the requirements, level-switching a ground-referenced signal having one operational amplifier while operating on a single-supply voltage. The non-inverting summing configuration of the operational amplifier makes the level-shifted output by adding a reference voltage with the input signal.
