Abstract: An ADC system may include an ADC, a comparator, a voltage source, a comparator output polarity control circuit and a comparator output counter. An analog input signal may be input to a first input of the comparator, and an output of the voltage source may be input to a second input of the comparator. The comparator may generate an output to the comparator output polarity control circuit, and the comparator output counter may count clock cycles while the comparator output is asserted and may assert a monitor output based on the comparator output counter value. The monitor output may be an interrupt, an alarm or other system alerts and may control system operation.

Abstract: A multi-channel ADC system may include a plurality of input channels coupled to input signals. A multiplexer may couple one or more of the plurality of input channels to one or more multiplexer output channels. A control circuit may be coupled between the multiplexer output channels and an ADC. In operation, a configuration setting may configure the multi-channel ADC system in one of a plurality of configurations, including but not limited to single-ended, differential, pseudo-differential and hybrid configurations. The ADC may convert the plurality of input channels based on the configuration setting.
