Abstract
A method and apparatus provide fuse trimming of analog integrated circuit parameters in plastic packages. The apparatus includes an electrically interruptible circuit element, such as a fuse; a level reading unit which reads the state of the electrically interruptible circuit element and generates a code in response to the state; a state altering unit, such as a current source for providing a blow current; and a control circuit. A test level reading device allows screening for marginally-blown fuses. A switchable element removes applied voltage from fuses when the fuse is not being blown or read to prevent fuse regrowth.
