Abstract
Domestic digital power supply has become an indispensable product in power supply chips,and the accuracy of the analog-to-digital converter(ADC)chip inside its internal feedback control loop directly affects the accuracy and stability of the output of the whole power supply.The static parameters of the ADC,namely integral nonlinearity(INL)and differential nonlinearity(DNL),are the important indexes for evaluating the accuracy of the ADC.At present,the domestic equipment for testing the static parameters of ADC in digital power supply is complicated and costly,and is not independently controllable.Therefore,it is especially important to design a low-cost and easy-to-operate static parameter test system.An ADC static parameter test system based on STM32H7 is designed,and the accuracy and feasibility of the system are verified by experiments.关键词
