ANALOG-TO-DIGITAL
CONVERTER (A/D) MODULE
The Analog-to-Digital (A/D) Converter module has five
inputs.
The analog input charges a sample and hold capacitor.
The output of the sample and hold capacitor is the
input into the converter. The converter then generates
a digital result of this analog level via successive
approximation. The A/D conversion of the analog input
signal results in a corresponding 10-bit digital number.
The A/D module has high and low voltage reference
input that is software selectable to some combination
of V
DD
, V
SS
, RA2 or RA3.
The A/D converter has a unique feature of being able
to operate while the device is in SLEEP mode. To
operate in SLEEP, the A/D clock must be derived from
the A/D’s internal RC oscillator.
The A/D module has four registers. These registers
are:
A/D Result High Register (ADRESH)
A/D Result Low Register (ADRESL)
A/D Control Register0 (ADCON0)
A/D Control Register1 (ADCON1)
The ADCON0 register, shown in Register 10-1, con-
trols the operation of the A/D module. The ADCON1
register, shown in Register 10-2, configures the func-
tions of the port pins. The port pins can be configured
as analog inputs (RA3 can also be the voltage refer-
ence) or as digital I/O.
Additional information on using the A/D module can be
found in the PICmicro Mid-Range MCU Family Ref-
erence Manual (DS33023).
