Update: 28 September, 2023
This document describes six application cases of the two analog comparators embedded in the ultra low power STM32L1 product line. The application cases include: analog voltage monitoring, analog watchdog during Stop mode, pulse width measurement, pulse width modulation (PWM) signal control, capacitance measurement, and brightness control using a light dependent resistor (LDR). These application cases demonstrate the usefulness of analog comparators and show how they are integrated with other peripherals, such as the digital-to-analog converter (DAC) and timers.
