Abstract
Integrated circuit systems, such as sensor systems, having on-board-diagnostic (OBD) circuits for the detection of errors presenting internal to the systems are disclosed, along with related methods. In one embodiment, an ADC multiplexer receives analog output readback from an output driver and provides a signal triggering an OBD circuit for internal error indication performed completely independent of digital-to-analog converters (DAC) and output drivers, which can be the point of failure.
