X9315ZM Datasheet

E2POT Nonvolatile Digital Potentiometer


The Xicor X9315 is a solid state "micropower" nonvol atile potentiometer and is ideal for digitally controlled
resistance trimming.
The X9315 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 CS, U/D,
and INC inputs. The position of the wiper can be stored in nonvolatile memory and then be recalled upon a sub sequent power-up operation.
