CAUTION
When the multiple channel continuous scan mode is used, extra care
is needed in the design of circuitry driving the A/D inputs. Refer to the
A/D Pin Model and A/D Conversion Sequence figures in addition to
the following discussion. The charge on the capacitive DAC array pri-
or to the sample time is related to the voltage on the previously con-
verted channel. A charge share situation exists between the internal
DAC capacitance and the external circuit capacitance. Although the
amount of charge involved is small the rate at which it is repeated is
every 64 microseconds for an E clock of 2 MHz. The RC charging
rate of the external circuit must be balanced against this charge shar-
ing effect to avoid accuracy errors.
CD — Channel Select D
CC — Channel Select C
CB — Channel Select B
CA — Channel Select A
These four bits are used to select one of 16 A/D channels (see
Table 7-1
). When a
multiple channel mode is selected (MULT = 1), the two least-significant channel select
bits (CB and CA) have no meaning and the CD and CC bits specify which group of four
channels are to be converted. The channels selected by the four channel select control
bits are shown in
Table 7-1
.
*Not available in 48-pin package versions.
