com Description The Intersil HI3304 is a CMOS parallel (FLASH) analog-todigital converter designed for applications demanding both low-power consumption and high speed digitization.
Digitizing at 25MHz, for example, requires only about 35mW.
The HI3304 operates over a wide, full-scale signal input voltage range of 0.
5V up to the supply voltage.
Power consumption is as low as 10mW, depending upon the clock frequency selected.
Sixteen paralleled auto-balanced voltage comparators measure the input voltage with respect to a known reference to produce the parallel-bit outputs in the HI3304.
Fifteen comparators are required to quantize all input voltage levels in this 4-bit converter, and the additional comparator is required for the overflow bit.
A data change pin indicates when the present output differs from the previous, thus allowing compaction of data storage.
