1.3 Analog-to-Digital Converter with Computation Module (ADCC)

The PIC18-Q24 family of microcontrollers offers a 10-bit Successive Approximation Register (SAR) ADC, with up to 30 channels and with a sampling rate of up to 300 ksps at a 10-bit resolution. Furthermore, it supports Single-Ended mode ADC operations, where the ADC measures the voltage between the selected input and ground.

The built-in computational feature provides post-processing functions such as averaging, reference comparisons and threshold comparison. Depending on the result available post-processing, the module can accumulate more samples or stop conversions. The ADCC can be configured as required in one of five computational modes:
  • Average
  • Burst
  • Accumulate
  • Burst Average
  • Low-Pass Filter
