Frequently Asked Questions 1. As consumers continue to push for lower prices and higher performance, system suppliers must find new ways to contain costs while maintaining or even improving accuracy. The task becomes more difficult as supply voltages continue shrinking, magnifying the effect of error sources.
Many systems use manual or electronic calibration to eliminate offsets.
This is effective, but consumes additional labor and equipment. Controlling offsets at the component level reduces or eliminates the requirements for system calibration. Various trimming methods are used to minimize offset and increase precision in amplifiers. There are lots of other trim methods. The most important reason is cost.
