Temperature sensorThe temperature sensor (TSENSE) generates a voltage VSENSE that varies linearly withtemperature.The temperature sensor is internally connected to the ADC_IN16 input channel which isused to convert the sensor output voltage into a digital value.The sensor provides good linearity but it has to be calibrated to obtain good overall accuracyof the temperature measurement. As the offset of the temperature sensor varies from chipto chip due to process variation, the uncalibrated internal temperature sensor is suitable forapplications that detect temperature changes only.To improve the accuracy of the temperature sensor measurement, each device isindividually factory-calibrated by ST. The temperature sensor factory calibration data arestored by ST in the system memory area, accessible in read-only modeDAC (digital-to-analog converter)The two 12-bit buffered DAC channels can be used to convert two digital signals into twoanalog voltage signal outputs. The chosen design structure is composed of integratedresistor strings and an amplifier in non-inverting configuration.This dual digital Interface supports the following features:●two DAC converters: one for each output channel●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 triggeredthrough the timer update outputs that are also connected to different DMA channel
