ADC (analog-to-digital converter)
A 12-bit analog-to-digital converters is embedded into STM32L15xxx devices with up to 24
external channels, performing conversions in single-shot or scan mode. In scan mode,
automatic conversion is performed on a selected group of analog inputs.
The ADC can be served by the DMA controller.
An analog watchdog feature allows very precise monitoring of the converted voltage of one,
some or all selected channels. An interrupt is generated when the converted voltage is
outside the programmed thresholds.
The events generated by the general-purpose timers (TIMx) can be internally connected to
the ADC start trigger and injection trigger, to allow the application to synchronize A/D
conversions and timers.
The ADC includes a specific low power mode. The converter is able to operate at maximum
speed even if the CPU is operating at a very low frequency and has an auto-shutdown
function. The ADC’s runtime and analog front-end current consumption are thus minimized
whatever the MCU operating mode.
Temperature sensor
The temperature sensor has to generate a voltage that varies linearly with temperature. The
conversion range is between 1.8 V < VDDA < 3.6 V. The temperature sensor is internally
connected to the ADC_IN16 input channel.
3.11
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:
●
two DAC converters: one for each output channel
●
up to 10-bit output
●
left or right data alignment in 12-bit mode
●
synchronized update capability
●
noise-wave generation
●
triangular-wave generation
●
dual DAC channels’ independent or simultaneous conversions
●
DMA capability for each channel (including the underrun interrupt)
●
external triggers for conversion
●
input reference voltage VREF+
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.
