Introduction
Basic 8-bit
Converter
A/D
This 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. The
output of the sample and hold is the input into the converter, which generates the result via suc-
cessive approximation. The analog reference voltage is software selectable to either the device’s
positive supply voltage (V
unique feature of being able to operate while the device is in SLEEP mode.
The A/D module has three registers. These registers are:
The ADCON0 register, shown in
ADCON1 register, shown in
can be configured as analog inputs (or a voltage reference) or as digital I/O.
