The 10-bit A/D Converter has the following key
features:
• Successive Approximation (SAR) conversion
• Conversion speeds of up to 500 ksps
• Up to 13 analog input pins
• External voltage reference input pins
• Automatic Channel Scan mode
• Selectable conversion trigger source
• 16-word conversion result buffer
• Selectable Buffer Fill modes
• Four result alignment options
• Operation during CPU Sleep and Idle modes
Depending on the particular device pinout, the 10-bit
A/D Converter can have up to three analog input pins,
designated AN0 through AN12. In addition, there are
two analog input pins for external voltage reference
connections. These voltage reference inputs may be
shared with other analog input pins. The actual number
of analog input pins and external voltage reference
input configuration will depend on the specific device.
