106 / 147 page  Electrical characteristics STM32L072xx 106/147 DocID027100 Rev 3 Figure 34. 12-bit buffered/non-buffered DAC 6.3.17 Temperature sensor characteristics 6. Difference between the value measured at Code (0x800) and the ideal value = VREF+/2. 7. Difference between the value measured at Code (0x001) and the ideal value. 8. Difference between ideal slope of the transfer function and measured slope computed from code 0x000 and 0xFFF when buffer is off, and from code giving 0.2 V and (VDDA – 0.2) V when buffer is on. 9. In buffered mode, the output can overshoot above the final value for low input code (starting from min value). Table 68. 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 130 °C, VDDA= 3 V 0x1FF8 007E - 0x1FF8 007F Table 69.
