101 / 133 page  DocID17659 Rev 12 101/133 STM32L151x6/8/B STM32L152x6/8/B Electrical characteristics 104 Figure 31. 12-bit buffered /non-buffered DAC 1. The DAC integrates an output buffer that can be used to reduce the output impedance and to drive external loads directly without the use of an external operational amplifier. The buffer can be bypassed by configuring the BOFFx bit in the DAC_CR register. 6.3.19 Temperature sensor characteristics Table 58. Temperature sensor calibration values Calibration value name Description Memory address TS_CAL1 TS ADC raw data acquired at temperature of 30 °C, VDDA= 3 V 0x1FF8 007A-0x1FF8 007B TS_CAL2 TS ADC raw data acquired at temperature of 110 °C VDDA= 3 V 0x1FF8 007E-0x1FF8 007F Table 59. Temperature sensor characteristics Symbol Parameter Min Typ Max Unit TL(1) 1. Guaranteed by characterization results.
