14 High-Speed, 12-Bit Analog-to-Digital Converter

Note:
  1. This data sheet summarizes the features of the dsPIC33CK512MPT608 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to “12-Bit High-Speed, Multiple SARs A/D Converter (ADC)” (www.microchip.com/DS70005213) in the “dsPIC33/PIC24 Family Reference Manual”.
  2. Some registers and associated bits described in this section may not be available on all devices due to the number of implemented ADC channels. Refer to dsPIC33CK512MPT608 Product Families for ADC channel availability on device variants.

dsPIC33CK512MPT608 devices have a high-speed, 12-bit Analog-to-Digital Converter (ADC) that features a low conversion latency, high resolution and oversampling capabilities to improve performance in AC/DC and DC/DC power converters. The devices implement the ADC with five SAR cores, four dedicated and one shared.

The number of available channels and negative inputs is dependent on package size, as shown in the table below.
