ABSTRACT:
An integrated circuit includes a plurality of circuit groups, each circuit group containing a plurality of analog inputs, a buffer, a sample/hold circuit and a comparator. Each buffer has an input to which any of the analog inputs in its group may be programmably connected. The output of each buffer is coupled to the input of the sample/hold circuit in the group. The output of each sample/hold circuit is coupled to one input of a multiplexer. The output of the multiplexer is coupled to the input of an amplifier having programmable gain and programmable offset. The comparator in each group has inputs that may be programmably coupled to at least one analog input in the group or to a reference voltage source.
