Internal voltage reference (V
The internal voltage reference (V
ADC and Comparators. V
enables accurate monitoring of the V
available for ADC). The precise voltage of V
ST during production test and stored in the system memory area. It is accessible in read-
only mode.

DAC (digital-to-analog converter)
The two 12-bit buffered DAC channels can be used to convert two digital signals into two
analog voltage signal outputs. The chosen design structure is composed of integrated
resistor strings and an amplifier in non-inverting configuration.
This dual digital Interface supports the following features:

Eight DAC trigger inputs are used in the STM32L15xxx. The DAC channels are triggered
through the timer update outputs that are also connected to different DMA channels.
Ultra-low-power comparators and reference voltage
The STM32L15xxx embeds two comparators sharing the same current bias and reference
voltage. The reference voltage can be internal or external (coming from an I/O).
