Voltage level shifting in a switching output stage is presented. The circuit may include a switching output stage (202) configured to receive an analog input signal and provide a responsive digital output signal, the switching output stage (202) having a first switching device (304) coupled to a first supply voltage (302) and a second switching device (314) coupled to a second supply voltage (310), the first switching device (304) and the second switching device (314) being coupled to a common output node (308). The apparatus may also include a voltage level shifter circuit (210) coupled to a switching control node of the second switching device (314), the voltage level shifter (210) configured to shift a voltage level at the switching control node of the second switching device (314) relative to the analog input signal, wherein the digital output signal at the common output node transitions as the input signal reaches a predetermined threshold value.
