Abstract: Disclosed are a method and a device for improving an output accuracy of a digital-to-analog converter. The method includes: calculating an output error of the digital-to-analog converter based on output accuracy and an input error of the digital-to-analog converter; obtaining at least one of the output error, comparing the at least one output error against a preset threshold, and adjusting an integer input value of the digital-to-analog converter according to a comparison result.
