METHOD AND DEVICE FOR FUNCTIONALLY TESTING AN ANALOG-TO-DIGITAL CONVERTER, AND A CORRESPONDING ANALOG-TO-DIGITAL CONVERTER

摘要

The present invention relates to a kind of device and method, for functionally testing analog-digital converter (ADC1), thus at least one of analog-digital converter progress function is used to be converted at least one analog signal digital signal, while utilizing the first predetermined reference voltage (UREF1). It is a feature of the present invention that analog-digital converter can optionally execute function, while additional using at least one, especially scheduled second reference voltage. Analog-digital converter, the analog-digital converter be deactivated in order to prevent from using at least one additional, particularly, the second reference voltage (UREF2) is in order to carry out functional test, predetermined analog signal is converted to digital signal, which is then evaluated.
