ANALOG-TO-DIGITAL
CONVERTER (A/D) MODULE
Applicable Devices
The analog-to-digital (A/D) converter module has four
analog inputs.
The A/D allows conversion of an analog input signal to
a corresponding 8-bit digital number (refer to Applica-
tion Note AN546 for use of A/D Converter). The output
of the sample and hold is the input into the converter,
which generates the result via successive approxima-
tion. The analog reference voltage is software select-
able to either the device’s positive supply voltage (V
DD
)
or the voltage level on the RA3/AN3/V
REF
pin.

The A/D converter has a unique feature of being able
to operate while the device is in SLEEP mode. To oper-
ate in sleep, the A/D conversion clock must be derived
from the A/D’s internal RC oscillator.
The A/D module has three registers. These registers
are:
A/D Result Register (ADRES)
A/D Control Register 0 (ADCON0)
A/D Control Register 1 (ADCON1)
The ADCON0 register, shown in Figure 7-1 and
Figure 7-2, controls the operation of the A/D module.
The ADCON1 register, shown in Figure 7-3 configures
the functions of the port pins. The port pins can be con-
figured as analog inputs (RA3 can also be a voltage ref-
erence) or as digital I/O.
