Abstract
An integrated circuit is provided that includes an output stage circuit. The output stage circuit includes an input node for receiving a digital input signal, a supply voltage node for receiving a supply voltage signal, a digital to analog convertor for converting the digital signal, an amplifier for amplifying the converted signal, a first/second and optionally third voltage regulator generating a first/second and optionally third voltage signal, and a greatest-voltage selector circuit for providing power to the amplifier. Two different voltages are provided to the DAC. The output signal can be a SENT signal. The circuit is highly robust against power-interruptions and EMI.
