84 / 119 page  Electrical characteristics STM32L011x3/4 84/119 DocID027973 Rev 5 Figure 28. Typical connection diagram using the ADC 1. Refer to Table 54: ADC characteristics for the values of RAIN, RADC and CADC. 2. Cparasitic represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the pad capacitance (roughly 7 pF). A high Cparasitic value will downgrade conversion accuracy. To remedy this, fADC should be reduced. 6.3.16 Temperature sensor characteristics Table 57. Temperature sensor calibration values Calibration value name Description Memory address TS_CAL2 TS ADC raw data acquired at temperature of 130 °C ± 5°C, VDDA= 3 V ± 10 mV 0x1FF8 007E - 0x1FF8 007F Table 58. Temperature sensor characteristics Symbol Parameter Min Typ Max Unit TL(1) 1. Guaranteed by characterization results, not tested in production.
