The 10-bit A/D Converter has the following key
features:
• Successive Approximation (SAR) Conversion
• Conversion Speeds of up to 500 ksps
• 16 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 PIC24FJ256GA110 family devices, the 10-bit
A/D Converter has 16 analog input pins, designated
AN0 through AN15. In addition, there are two analog
input pins for external voltage reference connections
(V
may be shared with other analog input pins.
