Abstract：Following the rapid development of digitization，digital multimedia products，e. g. cellular phones，digital cameras，and DVD/HPTV，etc. ，have been widely used. While in order to display the video signal，it is necessary to convert it into analog RGB/ YPbPr signal and amplify. A new video chip ISL59830 is introduced. The features，functions of pins and operational principle are presented. In addition，a typical application circuit is given. The chip offers excellent performance，simple peripheral circuit and can be used in video driver circuits of various display equipment.
