Description
The HI3306 family are CMOS parallel (FLASH) analog-to­digital converters designed for applications demanding both low power consumption and high speed digitization. Digitizing at 15MHz, for example, requires only about 55mW.
The HI3306 family operates ov er a wide , full scale signal input voltage range of 1V up to the supply voltage. Power consump­tion is as low as 15mW, depending upon the clock frequency selected. The HI3306 offers improved linearity at a lower ref­erence voltage and high operating speed with a 5V supply.
The overflow bit makes possible the connection of two or more HI3306s in series to increase the resolution of the conversion system.
Sixty-four paralleled auto balanced comparators measure the input voltage with respect to a known reference to pro­duce the parallel bit outputs in the HI3306. Sixty-three com­parators are required to quantize all input voltage levels in this 6-bit converter, and the additional comparator is required for the overflow bit.
