ADC12762 12-Bit, 1.4 MHz, 300 mW A/D Converter with Input Multiplexer and Sample/Hold
General Description
Using an innovative multistep conversion technique, the 12-bit ADC12762 CMOS analog-to-digital converter digitizes signals at a 1.4 MHz sampling rate while consuming a maximum of only 300 mW on a single +5V supply. The ADC12762 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.
