116 / 177 page  Electrical characteristics STM32F20xxx 116/177 Doc ID 15818 Rev 9 Equation 1: RAIN max formula The formula above (Equation 1) is used to determine the maximum external impedance allowed for an error below 1/4 of LSB. N = 12 (from 12-bit resolution) and k is the number of sampling periods defined in the ADC_SMPR1 register. fS (3) Sampling rate (fADC = 30 MHz) 12-bit resolution Single ADC -- 2 Msps 12-bit resolution Interleave Dual ADC mode - - 3.75 Msps 12-bit resolution Interleave Triple ADC mode -- 6 Msps IVREF+ (3) ADC VREF DC current consumption in conversion mode fADC = 30 MHz 3 sampling time 12-bit resolution - 300 500 µA fADC = 30 MHz 480 sampling time 12-bit resolution -- 16 µA IVDDA (3) ADC VDDA DC current consumption in conversion mode fADC = 30 MHz 3 sampling time 12-bit resolution -1.6 1.8 mA fADC = 30 MHz 480 sampling time 12-bit resolution -- 60 µA 1. If IRROFF is set to VDD, this value can be lowered to 1.7 V when the device operates in the 0 to 70 °C temperature range. 2. It is recommended to maintain the voltage difference between VREF+ and VDDA below 1.8 V. 3. Based on characterization, not tested in production. 4. VREF+ is internally connected to VDDA and VREF- is internally connected to VSSA. 5. RADC maximum value is given for VDD=1.8 V, and minimum value for VDD=3.3 V. 6. For external triggers, a delay of 1/fPCLK2 must be added to the latency specified in Table 64. Table 64.
