Patent ID: 7215176

Claim:
An analog value adjustment circuit comprising: 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, wherein the analog value output circuit comprises: a ladder resistor circuit comprising a plurality of resistor elements that are connected in series between a first node and a second node; and a select circuit that selects any one of a first through Kth taps of the ladder resistor circuit (K is an integer of two or more) based on the fuse data from the fuse circuit, and adjusts the analog value, and the select circuit selects a Lth tap (L is an integer and 1<L<K) corresponding to the typical value, when the fuse data from the fuse circuit is data indicating that all of the first through Nth fuse elements are in the non-cutting state, wherein 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, wherein in the ladder resistor circuit, the first through Kth taps are set so that the tape of a resistance of the resistor elements between taps becomes larger when being drawn closer to the first or Kth tap, and t he tap of the resistance of the resistor elements between taps becomes lower when being drawn closer to the Lth tap corresponding to the typical value.
