ADC0852 - Multiplexed Comparator

Description

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

ADC0852 ADC0854 Multiplexed Comparator with 8-Bit Reference Divider April 1995 ADC0852 ADC0854 Multiplexed Comparator with 8-Bit Reference Divider General Description 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 This allows for easy implementation of set-point on-off or ‘‘bang-bang’’ control systems with several advantages over previous devices The ADC0854 has a 4 input multiplexer that can be software configured for single ended pseudo-differential and full-differential modes of operation In addition the DAC’s reference input is brought
