Digital-to-analog conversion error correction method and related device

The embodiment of the invention provides a digital-to-analog conversion error correction method and a related device. The digital-to-analog conversion error correction method comprises the following steps: acquiring a current environment temperature; determining a target correction parameter corresponding to the current environment temperature; obtaining a reference voltage, and carrying out digital-to-analog conversion detection to obtain a detection voltage; and performing digital-to-analog conversion error correction according to the detection voltage and the target correction parameter to obtain a corrected target voltage. Different from the technical scheme of single correction in the prior art, the embodiment of the invention fully considers the influence of the temperature on the correction parameters, and considers that the correction parameters are easily influenced by the temperature to generate characteristic drift, different correction parameters are adopted for correction at different temperature
