CA3318
August 1997
CMOS Video Speed,
8-Bit, Flash A/D Converter
Description
The CA3318 is a CMOS parallel (FLASH) analog-to-digital
converter designed for applications demanding both low
power consumption and high speed digitization.
The CA3318 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
operated from a 5V supply at a clock frequency of 15MHz,
the typical power consumption of the CA3318 is 150mW.
The intrinsic high conversion rate makes the CA3318 ideally
suited for digitizing high speed signals. The over鏗俹w bit
makes possible the connection of two or more CA3318s in
series to increase the resolution of the conversion system. A
series connection of two CA3318s may be used to produce a
9-bit high speed converter. Operation of two CA3318s in
parallel doubles the conversion speed (i.e., increases the
sampling rate from 15MHz to 30MHz).
256 paralleled auto balanced voltage comparators measure
the input voltage with respect to a known reference to
produce the parallel bit outputs in the CA3318.
255 comparators are required to quantize all input voltage
levels in this 8-bit converter, and the additional comparator is
required for the over鏗俹w bit.
