3. If the reference value is lower than 2.4 V, there will be a performance degradation proportional to the reference supply
4. SNR, THD, SINAD parameters are valid for frequency bandwidth 20Hz - 1kHz. Input signal frequency is 300Hz (for

reference source is selected through the reference voltage selection bits (REFV<>”00” in SDADC_CR1 register), the
application must first configure REFV bits and then wait for capacitor charging. Recommended waiting time is 3 ms if 1 µF
capacitor is used.
If internal reference voltage is selected then this capacitor is charged through internal resistance - typ. 300 ohm. If internal
