DESCRIPTION

The Xicor X9511 is a push button controlled, potentiom-

eter 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

quent power-on operation.

The resolution of the X9511 is equal to the maximum

resistance value divided by 31. As an example, for the

X9511W (10K

Ω) each tap point represents 323Ω.

All Xicor nonvolatile products are designed and tested for

applications requiring extended endurance and data

retention.
