X9313ZSZ-3集成电路（IC）的数字电位计规格书PDF中文资料

The Intersil X9313 is a digitally controlled potentiometer

(XDCP). The device consists of a resistor array, wiper

switches, a control section, and nonvolatile memory. The

wiper position is controlled by a 3-wire interface.

The potentiometer is implemented by a resistor array

composed of 31 resistive elements and a wiper switching

network. Between each element and at either end are tap

points accessible to the wiper terminal. 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 subsequent power-up

operation.

The device can be used as a three-terminal potentiometer or

as a two-terminal variable resistor in a wide variety of

applications including:

• Control

• Parameter adjustments

• Signal processing
