摘要：
Digital potentiometer architecture is disclosed, composing of an integrated circuit containing multiple string arrays, each having a plurality of switching devices and an array of resistors. The insertion of an additional string array between the input terminals and the wiper, allows for the disconnection of a common string array and for the independent calibration of the resistance between each input terminal and the wiper.
