HI3306

HI3306 December 1997 6-Bit, 15 MSPS, Flash A/D Converter 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 over 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.
