ADC12662 12-Bit, 1.5 MHz, 200 mW A/D Converter with Input Multiplexer and Sample/Hold June 2001 ADC12662 12-Bit, 1.5 MHz, 200 mW A/D Converter with Input Multiplexer and Sample/Hold General Description Using an innovative multistep conversion technique, the 12-bit ADC12662 CMOS analog-to-digital converter digitizes signals at a 1.5 MHz sampling rate while consuming a maximum of only 200 mW on a single +5V supply. The ADC12662 performs a 12-bit conversion in three lower-resolution “flash” conversions, yielding a fast A/D without the cost and power dissipation associated with true flash approaches. The analog input voltage to the ADC12662 is tracked and held by an internal sampling...
