ABSTRACT:
An analog-to-digital conversion apparatus for converting a plurality of analog input signals may include a plurality of analog input, a plurality of sample and hold circuits, one or more analog-to-digital converters (ADCs), a plurality of trigger selection circuits, and one or more analog multiplexers. The analog inputs may receive an analog input signals. The sample and hold circuits may include an input selectively coupled to at least one of the plurality of input and an output. The analog-to-digital converters (ADCs) may include an input and an output. The trigger selection circuits may selectively couple one of the inputs to one of the sample and hold circuits. The analog multiplexers may include a plurality of inputs selectively coupled to one or more of the sample and hold circuit outputs and an output coupled to one of the one or more analog-to-digital-converters.
