THEORY OF OPERATION
The CS5012A/14/16 family utilize a successive
approximation conversion technique. The analog
input is successively compared to the output of a
D/A converter controlled by the conversion algo-
rithm. Successive approximation begins by
comparing the analog input to the DAC output
which is set to half-scale (MSB on, all other bits
off). If the input is found to be below half-scale,
the MSB is reset to zero and the input is com-
pared to one-quarter scale (next MSB on, all
others off). If the input were above half-scale, the
MSB would remain high and the next compari-
son would be at three-quarters of full scale. This
procedure continues until all bits have been exer-
cised.
A unique charge redistribution architecture is
used to implement the successive approximation
algorithm. Instead of the traditional resistor net-
work, the DAC is an array of binary-weighted
capacitors. All capacitors in the array share a
common node at the comparator’s input. Their
other terminals are capable of being connected to
AIN, AGND, or VREF (Figure 1). When the de-
vice is not calibrating or converting, all capacitors
are tied to AIN forming Ctot. Switch S1 is closed
and the charge on the array, Qin, tracks the input
signal Vin (Figure 2a).
When the conversion command is issued, switch
S1 opens as shown in Figure 2b. This traps
charge Qin on the comparator side of the capaci-
tor array and creates a floating node at the
comparator’s input. The conversion algorithm op-
erates on this fixed charge, and the signal at the
analog input pin is ignored. In effect, the entire
DAC capacitor array serves as analog memory
