X9511WPI集成电路（IC）的数字电位计规格书PDF中文资料

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.
