Xicor® Adds High Voltage XDCP Product Family X9318-series
--New single supply 100-tap digitally controlled potentiometer for Higher Voltage applications
MILPITAS, California April 7, 2003 Xicor, Inc. (Nasdaq: XICO), a leading supplier of high performance mixed-signal integrated circuits, today introduced the X9318 family of 100-tap, nonvolatile digitally programmable potentiometers to expand its current broad offering of products. These potentiometers can operate up to 8 V, allowing extra dynamic range for higher voltage applications.
Operation at 8 V across the potentiometer is allowed while the digital control operates between 0 V and 5 V. The X9318 potentiometer features a 100-tap wiper with 99-segmented resistors and a Rtotal of 10k Ohm. Using the UP/DOWN interface, the system designer can adjust the wiper position to the setting that provides the optimal system performance. In addition this setting can be stored in the internal EEPROM memory. Overall, the device eliminates the need for an on-board microcontroller and lowers post-trim manufacturing costs for bias and control applications. Target applications include process controls requiring retention parameters, data acquisition systems requiring pre-configured voltage reference levels and signal conditioning circuits requiring zero offset and span correction in various sensors (such as temperature, pressure, IR, strain gauge, etc.). Other applications include power amplifier biasing for RF, audio and amplifiers that require gain or phase control.
"Xicor's provides cost-effective digital potentiometers that have voltages greater than 5 V. Many applications used for bias and control require signals between 2 V to 8 V," stated Tony Ochoa, marketing manager of Linear Products. "Often these higher voltages are seen in applications such as LCD bias control, DC bias adjustments of power amplifiers, gain and offset trim of amplifiers, laser diode bias control and voltage regulator output control."
Production samples are available in 8-lead SOIC and DIP packaging with 1k unit prices starting at $1.50 USD.
