Multiplexed Comparator With 8-bit Reference Divider

The ADC0852 and ADC0854 are CMOS devices that com- bine a versatile Analog input multiplexer, voltage compara- tor, and an 8-bit DAC which provides the Comparators threshold voltage (VTH). The Comparator provides a 1-bit output as a result of a comparison between the Analog input and the DACs 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-dif- ferential modes of operation. In addition the DACs refer- ence input is brought out to allow for reduction of the span. The ADC0852 has a two input multiplexer that CAN be con- figured as 2 single-ended or 1 differential input pair. The DAC reference input is internally tied to VCC. The multiplexer and 8-bit DAC are programmed via a serial data input word. Once programmed the output is updated once each Clock cycle up to a maximum Clock rate of 400 kHz.
