20.0
The dsPIC33FJ12MC201/202 devices have up to six
ADC module input channels.
The AD12B bit (ADxCON1<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.
20.1
The 10-bit ADC configuration has the following key
features:
• Successive Approximation (SAR) conversion
• Conversion speeds of up to 1.1 Msps
• Up to six 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
• Four result alignment options (signed/unsigned,
• Operation during CPU Sleep and Idle modes
• 16-word conversion result buffer
The 12-bit ADC configuration supports all the above
features, except:
• In the 12-bit configuration, conversion speeds of
• There is only one sample-and-hold amplifier in the

up to 500 ksps are supported
12-bit configuration, so simultaneous sampling of
multiple channels is not supported.

Key Features
This data sheet summarizes the features
of the dsPIC33FJ12MC201/202 family of
devices. It is not intended to be a compre-
hensive reference source. To complement
the information in this data sheet, refer to
the “dsPIC33F Family Reference Manual”,
Section 28. “Analog-to-Digital Converter
(ADC) without DMA” (DS70210), which is
available on the Microchip web site
(www.microchip.com).
The ADC module must be disabled before
the AD12B bit can be modified.
Preliminary
dsPIC33FJ12MC201/202
Depending on the particular device pinout, the ADC
can have up to six analog input pins, designated AN0
through AN5. 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.
Block diagrams of the ADC module are shown in
Figure 20-1 and Figure 20-2.
