9 Analog-to-Digital Converter
The analog-to-digital (A/D) converter system uses an all-capacitive charge-redistribution technique to
convert analog signals to digital values. The A/D converter system contained in M68HC11 K-series
MCUs is an 8-channel,8-bit, multiplexed-input, successive-approximation converter. It does not require
external sample and hold circuits.
The clock source for the A/D converter’s charge pump, like the clock source for the EEPROM charge
pump, is selected with the CSEL bit in the OPTION register. When the E clock is slower than 1 MHz,
the CSEL bit must be set to ensure that the successive approximation sequence for the A/D converter
will be completed before any charge loss occurs. In the case of the EEPROM, it is the efficiency of the
charge pump that is affected.
Figure 14 A/D Converter Block Diagram
The A/D converter can operate in single or multiple conversion modes. Multiple conversions are per-
formed in sequences of four. Sequences can be performed on a single channel or an a group of chan-
nels.
Dedicated lines V
RH
and V
RL
provide the reference supply voltage inputs.
