51.2 Features
The following are key features of the ADC module:
- Two Analog-to-Digital Converter (ADC): ADC0 and ADC1
- 8-bit, 10-bit, or 12-bit resolution
- Up to 1,000,000 samples per second (1Msps)
- Differential and single-ended inputs
- Up to 23 analog inputs per ADC
(16-external channels)
23 positive and 8 negative, including internal and external
- Up to 23 analog inputs per ADC
(16-external channels)
- Internal inputs:
- Scaled VDDCORE supply
- Scaled VDD supply
- Scaled VBAT supply
- DAC0
- Single, continuous, and sequencing options
- Windowing monitor with selectable channel
- Built-in internal reference and external reference options
- Event-triggered conversion for accurate timing (one event input)
- Optional DMA transfer of conversion settings or result
- Hardware gain and offset compensation
- Averaging and oversampling with decimation to support up to 16-bit result
- Selectable sampling time
- Flexible Power or Throughput rate management
ADC0 can be configured to serve the Peripheral Touch Controller (PTC). Refer to the PTC chapter for additional information.
