3.4.3 ADCC Low-Pass Filter Mode

The Low-Pass Filter mode can be used in systems where the control actions require a more stable signal from the input sensor. For example, in the case of a smartphone, while setting the brightness of the screen, the output of the ambient light sensor should be low-pass filtered.

Refer to AN2749 - Using PIC18F26K42's 12-bit ADC² in Low-Pass Filter Mode to understand the ADCC LPF mode in detail, which can be used for filtering noisy DC and AC signals.

Refer to the example below to understand how to use individual ADC Computation mode.
