Xicor Presents New X9318 Series Potentiometer

April 06, 2003 by Jeff Shepard

Xicor Inc. (Milpitas, CA), a supplier of high-performance, mixed-signal integrated circuits, introduced the X9318 family of 100-tap, non-volatile, digitally programmable potentiometers to expand its current offering of products. Target applications include process controls, data acquisition systems and signal conditioning circuits. Other applications include power amplifier biasing for RF, audio and amplifiers that require gain or phase control.

The potentiometers can operate at up to 8V, allowing extra dynamic range for higher-voltage applications. Operation at 8V across the potentiometer is allowed while the digital control operates between 0V and 5V. The X9318 potentiometer features a 100-tap wiper with 99 segmented resistors and a Rtotal of 10k Ohms. 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.

Production samples are available in eight-lead SOIC and DIP packaging with 1,000-unit pricing starting at $1.50.
