X9315WMI集成电路（IC）的数字电位计规格书PDF中文资料

Digitally Controlled Potentiometer (XDCP™)

The Intersil X9315 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.
