The CA3306 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 50mW.
The CA3306 family operates over a wide, full scale signal input volt-
age range of 1V up to the supply voltage. Power consumption is as
low as 15mW, depending upon the clock frequency selected. The
CA3306 types may be directly retrofitted into CA3300 sockets, offer-
ing improved linearity at a lower reference voltage and high operat-
ing speed with a 5V supply.
The intrinsic high conversion rate makes the CA3306 types ideally
suited for digitizing high speed signals. The overflow bit makes pos-
sible the connection of two or more CA3306s in series to increase
the resolution of the conversion system. A series connection of two
CA3306s may be used to produce a 7-bit high speed converter.
Operation of two CA3306s in parallel doubles the conversion speed
(i.e., increases the sampling rate from 15MHz to 30MHz).
Sixty-four paralleled auto balanced comparators measure the input
voltage with respect to a known reference to produce the parallel bit
outputs in the CA3306. Sixty-three comparators are required to
quantize all input voltage levels in this 6-bit converter, and the addi-
tional comparator is required for the overflow bit.
