PIC32 Family Reference Manual

22.1 INTRODUCTION

The PIC32 12-bit High-Speed Successive Approximation Register (SAR) Analog-to-Digital

Converter (ADC) includes the following features:

• 12-bit resolution

• Up to eight ADC modules with dedicated Sample and Hold (S&H) circuits (see Note 1)

• Two dedicated ADC modules can be combined in Turbo mode to provide double

conversion rate

• Single-ended and/or differential inputs

• Can operate during Sleep mode

• Supports touch sense applications

• Up to six digital comparators

• Up to six digital filters supporting two modes:

- Oversampling mode

- Averaging mode

• FIFO and DMA engine for dedicated ADC modules (see Note 2)

• Early interrupt generation resulting in faster processing of converted data

• Designed for motor control, power conversion, and general purpose applications

The dedicated ADC modules use a single input (or its alternate) and is intended for high-speed

and precise sampling of time-sensitive or transient inputs, whereas the shared ADC module

incorporates a multiplexer on the input to facilitate a larger group of inputs, with slower sampling,

and provides flexible automated scanning option through the input scan logic.

For each ADC module, the analog inputs are connected to the S&H capacitor. The clock,

sampling time, and output data resolution for each ADC module can be set independently. The

ADC module performs the conversion of the input analog signal based on the configurations set

in the registers. When conversion is complete, the final result is stored in the result buffer for the

specific analog input and is passed to the digital filter and digital comparator if configured to use

data from this particular sample.

A simplified block diagram of the ADC module is illustrated in Figure 22-1.

Note: This family reference manual section is meant to serve as a complement to device

data sheets. Depending on the device, this manual section may not apply to all

PIC32 devices.

Please refer to the note at the beginning of the “ADC” chapter in the current device

data sheet to check whether this document supports the device you are using.

Device data sheets and family reference manual sections are available for

download from the Microchip Worldwide Web site at: http://www.microchip.com

Note 1: Depending on the device, the 12-bit High-Speed SAR ADC has up to seven

dedicated ADC modules and one shared ADC module. Throughout this chapter,

the diagrams and code examples refer to a device with seven dedicated ADC

modules (ADC0-ADC6) and one shared ADC (ADC7). Please consult the “ADC”

chapter in the specific device data sheet to determine which ADC modules are

available for your device.

2: This feature is not available on all devices. Refer to the “ADC” chapter in the

specific device data sheet to determine availability.

3: Prior to enabling the ADC module, the user application must copy the ADC

calibration data (DEVADCx) from the Configuration memory into the ADC

Configuration registers (ADC0CFG-ADC7CFG). Refer to the “ADC” chapter in the

specific device data sheet for more information.
