DESCRIPTION
The Intersil X9511 is a push button controlled potentiometer that 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 subsequent power-on operation.
The resolution of the X9511 is equal to the maximum
resistance value divided by 31. As an example, for the
X9511W (10kΩ) each tap point represents 323Ω.
All Intersil nonvolatile products are designed and
tested for applications requiring extended endurance
and data retention.
