73 / 97 page ![]() STM32F050xx Electrical characteristics Doc ID 023683 Rev 1 73/97 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. Here N = 12 (from 12-bit resolution). Table 50. RAIN max for fADC = 14 MHz (1) 1. Guaranteed by design, not tested in production. Ts (cycles) tS (µs) RAIN max (kΩ) 1.5 0.11 0.4 7.5 0.54 5.9 13.5 0.96 11.4 28.5 2.04 25.2 41.5 2.96 37.2 55.5 3.96 50 71.5 5.11 NA 239.5 17.1 NA Table 51. ADC accuracy(1)(2) (3) 1. ADC DC accuracy values are measured after internal calibration.
