Abstract
A sensor configured to generate a sensor output signal at a sensor output coupled to a pull up voltage through a pull up resistor includes a sensing element configured to generate a sensing element output signal indicative of a sensed parameter and a processor responsive to the sensing element output signal and configured to generate a processor output signal indicative of the sensed parameter. A digital output controller is responsive to the processor output signal and to a digital feedback signal and is configured to generate a controller output signal. An analog output driver is responsive to the controller output signal and configured to generate the sensor output signal at a first predetermined level or at a second predetermined level and a feedback circuit coupled between the sensor output and the digital output controller is configured to generate the digital feedback signal in response to the sensor output signal.
