112 / 185 page  Electrical characteristics STM32WBA6xxx 112/185 DS14736 Rev 1 Figure 22. VREFINT vs. temperature 5.3.8 Supply current characteristics The current consumption is measured as described in Section 5.1.7. It depends upon several parameters, such as operating voltage, ambient temperature, I/O pin loading, device software configuration, operating frequency, I/O pin switching rate, program location in memory, and executed binary code. IDD(VREFINTBUF)(3) VREFINT buffer consumption from VDD when converted by ADC -- 1.5 2.1 μA ∆VREFINT(4) Internal reference voltage spread over the temperature range VDD = 3 V - 6 11.5 mV TCoeff(4) Average temperature coefficient –40 °C ≤ TJ ≤ +130 °C - 40 125 ppm/°C ACoeff(3) Long term stability 1000 hours, TJ = 25 °C - 400 1000 ppm VDDCoeff(4) Voltage coefficient 3.0 V ≤ VDD ≤ 3.6 V - 500 2900 ppm/V 1. VREFINT does not take into account package and soldering effects. 2. The shortest sampling time for the application can be determined by multiple iterations. 3. Specified by design, not tested in production. 4. Evaluated by characterization, not tested in production. Table 43.
