X9317WM8

DATASHEET X9317 FN8183 Rev.10.00 Dec 17, 2018 Low Noise, Low Power, 100 Taps, Digitally Controlled Potentiometer (XDCP™) 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. Features 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. • 100 wiper tap points - Wiper position stored in nonvolatile memory and recalled on power-up 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. • Low power CMOS - VCC = 2.7V to 5.5V, and 5V ±10% - Standby current
