Community Translation: FM4 MCU：ADCサンプリング時間に対する出力インピーダンスの影響
The ADC Sampling time “ts” changes with the external impedance. You must ensure that the output impedance of the external circuit is fixed and meets the A/D Converter Sampling time defined in the datasheet (for example the S6E2H Series datasheet.
