Digital-analog conversion circuit and output data correction method of the same
Abstract:
A digital-analog conversion circuit includes a correction unit that adds a correction bit to a lower-order bit of externally input first digital input data and outputs second digital input data, and a conversion unit that receives the second digital input data and outputs an analog value, and the correction unit generates the second digital input data by manipulating data of a lower-order bit of the second digital input data around a point at which an error between the analog value and an expected value set for the first digital input data becomes larger than a preset value.
