Claim:
1. A monolithic integrated circuit sensor system comprising: a first multiplexer in a first signal channel; a first analog-to-digital converter (ADC) in the first signal channel and coupled to the first multiplexer; a second multiplexer in a second signal channel; a second analog-to-digital converter (ADC) in the second signal channel and coupled to the second multiplexer; and a first sensor device configured to sense a physical characteristic, wherein the first sensor device is coupled to both the first and second ADCs to provide a signal related to the physical characteristic to both the first and second ADCs, the first sensor device being coupled to the first ADC by the first multiplexer and the first sensor device being coupled to the second ADC by the second multiplexer, wherein the sensor system is configured to detect an error in the sensor system based on a comparison of signals between the first and second signal channels after the first and second ADCs.
