ADC0854 Datasheet | National Semiconductor

Description The ADC0852 and ADC0854 are CMOS devices that bine a versatile analog input multiplexer voltage parator and an 8-bit DAC which provides the parator’s threshold voltage (VTH) The parator provides a ‘‘1-bit’’ output as a result of a parison 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 out to allow for reduction of the span The ADC0852 has a two input multiplexer that can be configured as 2 single-ended or 1 differential input pair The DAC reference input...
