Description
The HI3306 family are CMOS parallel (FLASH) analog-to-
digital 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 consump-
tion is as low as 15mW, depending upon the clock frequency
selected. The HI3306 offers improved linearity at a lower ref-
erence 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 pro-
duce the parallel bit outputs in the HI3306. Sixty-three com-
parators are required to quantize all input voltage levels in
this 6-bit converter, and the additional comparator is
required for the overflow bit.
