DATASHEET X9315 FN8179 Rev.2.00 Low Noise, Low Power, 32 Taps Digitally Controlled Potentiometer December 21, 2009 (XDCP) The Intersil X9315 is a digitally controlled potentiometer Features (XDCP). The device consists of a resistor array, wiper Solid-state potentiometer switches, a control section, and nonvolatile memory. The wiper position is controlled by a 3-wire interface. 3-wire serial interface The potentiometer is implemented by a resistor array 32 wiper tap points composed of 31 resistive elements and a wiper switching - Wiper position stored in nonvolatile memory and network. Between each element and at either end are tap recalled on power-up points accessible to the wiper terminal. The position of the 31 resistive elements wiper element is controlled by the CS, U/D, and INC inputs. - Temperature compensated The position of the wiper can be stored in nonvolatile - End to end resistance range 20% memory and then be recalled upon a subsequent power-up - Terminal voltage, 0 to V CC operation. Low power CMOS The device can be used as a three-terminal potentiometer or -V = 2.7V or 5V CC as a two-terminal variable resistor in a wide variety of - Active current, 80/400A max. applications including: - Standby current, 5A max.
