115 / 149 page  DocID026289 Rev 6 115/149 STM32F411xC STM32F411xE Electrical characteristics 123 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. Table 66. ADC accuracy at fADC = 18 MHz(1) 1. Better performance could be achieved in restricted VDD, frequency and temperature ranges. Symbol Parameter Test conditions Typ Max(2) 2. Guaranteed by characterization results. Unit ET Total unadjusted error fADC =18 MHz VDDA = 1.7 to 3.6 V VREF = 1.7 to 3.6 V VDDA −VREF < 1.2 V ±3 ±4 LSB EO Offset error ±2 ±3 EG Gain error ±1 ±3 ED Differential linearity error ±1 ±2 EL Integral linearity error ±2 ±3 Table 67. ADC accuracy at fADC = 30 MHz(1) 1. Better performance could be achieved in restricted VDD, frequency and temperature ranges. Symbol Parameter Test conditions Typ Max(2) 2. Guaranteed by characterization results. Unit ET Total unadjusted error fADC = 30 MHz, RAIN < 10 kΩ, VDDA = 2.4 to 3.6 V, VREF = 1.7 to 3.6 V, VDDA −VREF < 1.2 V ±2 ±5 LSB EO Offset error ±1.5 ±2.5 EG Gain error ±1.5 ±4 ED Differential linearity error ±1 ±2 EL Integral linearity error ±1.5 ±3 Table 68. ADC accuracy at fADC = 36 MHz(1) 1. Better performance could be achieved in restricted VDD, frequency and temperature ranges. Symbol Parameter Test conditions Typ Max(2) 2. Guaranteed by characterization results. Unit ET Total unadjusted error fADC =36 MHz, VDDA = 2.4 to 3.6 V, VREF = 1.7 to 3.6 V VDDA −VREF < 1.2 V ±4 ±7 LSB EO Offset error ±2 ±3 EG Gain error ±3 ±6 ED Differential linearity error ±2 ±3 EL Integral linearity error ±3 ±6 RAIN k0.5 – () fADC CADC 2 N 2 + () ln × × ---------------------------------------------------------------- RADC – = |
