The10-bit high-speed analog-to-digital converter (A/D)
allows conversion of an analog input signal to a 10-bit
digital number. This module is based on a Successive
Approximation Register (SAR) architecture, and provides
a maximum sampling rate of 500 ksps. The A/D module
has 16 analog inputs which are multiplexed into four
sample and hold amplifiers. The output of the sample and
hold is the input into the converter, which generates the
result. The analog reference voltages are software
selectable to either the device supply voltage (AV
AV
A/D converter has a unique feature of being able to
operate while the device is in Sleep mode.

The A/D module has six 16-bit registers:
• A/D Control register1 (ADCON1)
• A/D Control register2 (ADCON2)
• A/D Control register3 (ADCON3)
• A/D Input Select register (ADCHS)
• A/D Port Configuration register (ADPCFG)
• A/D Input Scan Selection register (ADCSSL)
The ADCON1, ADCON2 and ADCON3 registers
control the operation of the A/D module. The ADCHS
register selects the input channels to be converted. The
ADPCFG register configures the port pins as analog
inputs or as digital I/O. The ADCSSL register selects
inputs for scanning.
The block diagram of the A/D module is shown in
Figure 19-1.

The
SMPI<3:0>, BUFM and ALTS bits, as well
as the ADCON3 and ADCSSL registers,
must not be written to while ADON = 1.
This would lead to indeterminate results.
