Overview
Description
The X9317 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 99 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 for voltage control or as a two-terminal variable resistor for current control in a wide variety of applications.

Can I use a DCP in a video application?
Yes. We have an application note AN1481 that can assist you. It uses X9317 in the circuit examples, but it applies to our other DCPs as well. By selecting the proper DCP, the circuit bandwidth can be extended to sufficiently support NTSC and PAL, as well as HDTV video. Link ...
