DESCRIPTION

The Xicor X9511 is a push button controlled, potentiometer and is ideal for push button controlled resistance trimming.

The X9511 is a resistor array composed of 31 resistive elements. Between each element and at either end are tap points accessible to the wiper element. The position of the wiper element is controlled by the PU and PD inputs. The position of the wiper can be automatically stored in E2 memory and then be recalled upon a subse quent power-on operation.
