ADRESH Register: This register stores higher or lower bits of digital conversion result after the A/D converter produces a 10-bit digital number. We will see details of all these features later on. We use these registers to configure features such as sampling rate, A/D clock, channel selection, voltage reference for ADC and format of result that how the result will be stored. Pic microcontroller analog to digital converter module has five registers. Please refer to this Analog to Digital Converter Article, to understand its working. The A/D conversion technique uses a successive approximation (SAR) technique. This digital value is equivalent to its analog input signal. After that, a digital converter changes analog value into a 10-bit digital value. The output of charge/hold capacitor feds to an input of the digital converter. Firstly, each channel accepts analog inputs which charges charge and hold capacitor. How PIC18F ADC Works?ĪDC mainly consists of charge/hold capacitor and successive approximation converter.

However, control and configurations registers are the same for every PIC18F series microcontrollers. But the actual number of channels depends on the microcontroller, you are using. In other words, it can have up to sixteen ADC channels. Each microcontroller can accept up to 16 analog inputs.
