Functional Description The ADC0844 and ADC0848 contain a 4-channel and 8- channel analog input multiplexer (MUX) respectively. Each MUX can be configured into one of three modes of operation differential, pseudo-differential, and single ended. These modes are discussed in the ...

REFERENCE CONSIDERATIONS The voltage applied to the reference input of these converters defines the voltage span of the analog input (the difference between V and V ) over which the 256 possible IN(MAX) IN(MIN) output codes apply. The devices ...
