  • Patent number: 7215176
    Abstract: An analog value adjustment circuit includes a fuse circuit that outputs fuse data whose value changes corresponding to whether first through Nth (N is an integer of two or more) fuse elements are in a cutting state, or in a non-cutting state and an analog value output circuit that receives the fuse data from the fuse circuit, and outputs an analog value that is adjusted in a given adjustment range corresponding to the fuse data. When the fuse data from the fuse circuit is data indicating that all the first through Nth fuse elements are in the non-cutting state, the analog value output circuit outputs the analog value with a typical value that is a value between a maximum value and a minimum value in the given adjustment range.
