ADC0852 Datasheet (National Semiconductor)

ADC0852, Multiplexed Comparator

The ADC0852 and ADC0854 are CMOS devices that combine a versatile analog input multiplexer voltage comparator and an 8-bit DAC which provides the comparator’s threshold voltage (VTH) The comparator provides a ‘‘1-bit’’ output as a result of a comparison between the analog input and the DAC’s output
