A/D Comparator
The PIC14000 includes a high gain comparator for
A/D conversions. The positive input terminal of the A/D
comparator is connected to the output of an analog
mux through an RC low-pass lter. The nominal
time-constant for the RC lter is 3.5
s. The negative
input terminal is connected to the external 0.1
F (nom-
inal) ramp capacitor.
8.5
Analog Mux
A total of 16 channels are internally multiplexed to the
single
A/D
comparator
positive
input.
Four
conguration bits (ADCON0<7:4>) select the channel
to be converted. Refer to Table 8-1 for channel assign-
ments.
