![]() With the help of PRS and DMA, the ADC can operate without CPU intervention, minimizing current consumption or allow the core to do other work. The integrated input mux can select ADC-input from 8 external pins or 6 internal signals. The maximum resolution is 12 bits, and one million samples per second can be achieved at this resolution. This application note includes: This PDF document Source files (zip) Example C-code Multiple IDE projectsĢ 1 Analog to Digital Converter 1.1 Introduction.the world's most energy friendly microcontrollers The EFM32 ADC is a Successive Approximation Register (SAR) architecture. Calibration routines for offset and gain are also included. Many aspects of the ADC, including inputs, references and the different operating modes are described. 1 Analog to Digital Converter AN Application Note Introduction This application note describes how to use the EFM32 Analog to Digital Converter to convert an analog input voltage to a digital value.
