18.0
The PIC24HJ32GP202/204 and PIC24HJ16GP304
devices have up to 13 Analog-to-Digital Conversion
(ADC) module input channels.
The AD12B bit (AD1CON1<10>) allows each of the
ADC modules to be configured as either a 10-bit,
4-sample-and-hold ADC (default configuration), or a
12-bit, 1- sample and hold ADC.
18.1
The 10-bit ADC configuration has the following key
features:
• Successive Approximation (SAR) conversion
• Conversion speeds of up to 1.1 Msps
• Up to 13 analog input pins
• External voltage reference input pins
• Simultaneous sampling of up to four analog input
• Automatic Channel Scan mode
• Selectable conversion trigger source
• Selectable Buffer Fill modes
• Operation during CPU Sleep and Idle modes
• 16-word conversion result buffer

• There is only 1 sample-and-hold amplifier in the
Depending on the particular device pinout, the ADC
can have up to 13 analog input pins, designated AN0
through AN12. In addition, there are two analog input
pins for external voltage reference connections. These
voltage reference inputs can 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. Refer to the device data sheet for
further details.
