DESCRIPTION
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 posi-
tion 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.
The resolution of the X9315 is equal to the maximum
resistance value divided by 31. As an example, for the
X9315W (10K
) each tap point represents 323
.
All Xicor nonvolatile digital potentiometers are de-
signed and tested for applications requiring extended
endurance and data retention.
