A trim DAC wherein the digital input bits to the trim DAC are controlled by a state machine to produce an analog output that is within a least significant bit of the digital input bits. An undersize factor between digital input bits is used to assist in finding a trim solution for major transitions of the digital input bits. Trim solutions are stored in a nonvolatile memory associated with the state machine to be used in creating an accurate analog output. |
