12-bit, 1.5 Mhz, 200 Mw A/d Converter With Input Multiplexer And Sample/hold - National Semiconductor

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 maxi- mum 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 with- out 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 circuit, allowing high frequency input signals to be accurately digitized without the need for an external sample-and-hold circuit. The ADC12662 features two sample-and-hold Flash Comparator sections which allow the converter to acquire one sample while converting the previous. This pipelining technique increases conversion speed without sacrificing performance. The multiplexer out- put is available to the user in order to perform additional external signal processing before the signal is digitized. When the converter is not digitizing signals, it CAN be placed in the Standby mode; typical power consumption in this mode is 250 W. By National Semiconductor Corporation
