Description
The HI3318 is a CMOS parallel (FLASH) analog-to-digital
converter designed for applications demanding both low
power consumption and high speed digitization.
The HI3318 operates over a wide full scale input voltage
range of 4V up to 7.5V with maximum power consumption
depending upon the clock frequency selected. When oper-
ated from a 5V supply at a clock frequency of 15MHz, the
typical power consumption of the HI3318 is 150mW.
256 paralleled auto balanced voltage comparators measure
the input voltage with respect to a known reference to pro-
duce the parallel bit outputs in the HI3318. 255 comparators
are required to quantize all input voltage levels in this 8-bit
converter, and the additional comparator is required for the
overflow bit.
