172 / 228 page ![]() Electrical characteristics STM32H523xx 172/228 DS14540 Rev 1 Note: ADC accuracy vs. negative injection current: injecting a negative current on any analog input pins should be avoided as this significantly reduces the accuracy of the conversion being performed on another analog input. It is recommended to add a Schottky diode (pin to ground) to analog pins, which may potentially inject negative currents. Table 91. ADC accuracy(1)(2) Symbol Parameter Conditions Min Typ Max Unit ET Total unadjusted error Fast and slow channels Single ended - ±3.5 ±12 LSB Differential - ±2.5 ±7.5 EO Offset error - Single ended - ±3 ±5.5 - Differential - ±2 ±3.5 EG Gain error - Single ended - ±3.5 ±11 - Differential ±2.5 ±7 ED Differential linearity error - Single ended - ±0.75 +2/-1 - Differential - ±0.75 +2/-1 EL Integral linearity error Fast and slow channels Single ended - ±2 ±6.5 Differential - ±1 ±4 ENOB Effective number of bits Single ended - 10.8 - Bits Differential - 11.5 - SINAD Signal-to-noise and distortion ratio Single ended - 68 - dB Differential - 71 - SNR Signal-to-noise ratio Single ended - 70 - Differential - 72 - THD Total harmonic distortion Single ended - -70 - Differential - -80 - 1. Evaluated by characterization for BGA packages. The values for LQFP package can differ. Not tested in production. 2. ADC DC accuracy values are measured after internal calibration in continuous mode. |
