Application note
Analog-to-digital audio conversion example using
STM32L4 Series microcontroller peripherals
Introduction
The purpose of this application note is to provide an analog-to-digital audio conversion
example using the STM32L4 Series microcontroller peripherals (OPAMP, ADC and the
Full-Speed USB).
This example uses the ADC dedicated features to improve the conversion resolution and to
automatically detect a programmable threshold level.
Note that the values provided in this application note are for reference only, measured in a
laboratory under typical conditions (unless otherwise specified) and not tested in production.
