The 10-bit A/D Converter has the following key
features:
• Successive Approximation (SAR) conversion
• Conversion speeds of up to 500 ksps
• 13 analog input pins
• External voltage reference input pins
• Internal band gap reference inputs
• 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
On all PIC24FJ64GB004 family devices, the 10-bit A/D
Converter has 13 analog input pins, designated AN0
through AN12. In addition, there are two analog input
pins for external voltage reference connections (V
and V
shared with other analog input pins.
