CMOS, High-Speed, 8-Bit ADCs with Multiplexer _______________Detailed Description Converter Operation The MAX154/MAX158 and MX7824/MX7828 use what is commonly called a “half-flash” conversion technique (Figure 3). Two 4-bit flash ADC sections are used to achieve an 8-bit result. Using 15 comparators, ...
