Title:
D/A変換器
Document Type and Number:
Japanese Patent JP4901706
Kind Code:
B2
Abstract:
A D/A converter has a reference comparison current generator configured to generate a reference comparison current, a first reference current generator configured to generate a first reference current capable of correcting a current level, a first D/A converting part capable of outputting a first full-scale current having a predetermined proportional relationship with the first reference current and capable of generating a first D/A converting voltage in accordance with first input digital data, and a current comparator configured to generate a difference current between the first full-scale current and the reference comparison current to determine a magnitude of the difference current. The first reference current generator corrects the first reference current based on a result determined by the current comparator.
