73 / 91 page  DS12323 Rev 3 73/91 STM32L010F4/K4 Electrical characteristics 81 Equation 1: RAIN max formula The presented formula above (Equation 1) is a representation of an hypothetical ideal ADC and illustrates how the parameters influence each other. It is not to be used for computation of actual values. tSTAB(3) Power-up time - 0 0 1 µs tConV(3) Total conversion time (including sampling time) fADC = 16 MHz 0.875 - 10.81 µs - 14 to 173 (tS for sampling +12.5 for successive approximation) 1/fADC 1. VDDA minimum value can be decreased in specific temperature conditions. Refer to Table 53: RAIN max for fADC = 16 MHz. 2. A current consumption proportional to the APB clock frequency has to be added Refer to Table 29: Peripheral current consumption in run or Sleep mode. 3. Guaranteed by design, not tested in production. 4. Standard channels have an extra protection resistance which depends on supply voltage. Refer to Table 53: RAIN max for fADC = 16 MHz. Table 52.
