Intersil Wins Electronic Products “Product of the Year” Award

Editors Recognize Patent-Pending Design and Industry-Leading Performance of Intersil’s ISL22317 Digitally Controlled Potentiometer

MILPITAS, CA — January 6, 2010 — Intersil Corporation (NASDAQ Global Select: ISIL), a leader in the design and manufacture of analog and mixed-signal semiconductors, today announced that editors of Electronic Products Magazine have selected the ISL22317 as one of its “Products of the Year” for 2009.  

The editors of Electronic Products—a leading trade publication for electronic design engineers— evaluated thousands of products launched in 2009. The winning products are selected on the basis of innovative design, significant advancement in technology or application and substantial achievement in price and performance. Intersil’s ISL22317 took top honors in the “Analog and Mixed Signal” division of the annual competition.

Winning Technical Features and Benefits
The ISL22317 is the industry’s first low-voltage DCP with < 1 percent typical resistor tolerance.  The ultra-low tolerance allows the ISL22317 to be used as a true variable resistor, enabling users to set standard and non-standard resistor values for open-loop applications.

The ISL22317 is an excellent choice for designs that require specific current and resistor values such as test and measurement circuits, medical devices, backlight controls, or adjusting specific resistances in analog circuits.  The patent-pending architecture of the ISL22317 allows it to track an external resistor within 10ppm/degree C, improving overall system accuracy for temperatures up to 125 degrees C.  

The ISL22317 reduces programming time and development costs by letting users select accurate pre-determined resistor values, and use calculated resistor values in schematics. In addition, it allows one to use the known value of one system to calibrate other systems. The device employs an easy-to-use I2C interface to program accurate resistor settings >1 million times in the integrated EEPROM memory.

The ISL22317 also features a zero-compensated wiper resistance in rheostat mode.  By negating wiper resistance, overall accuracy is improved, especially at the low tap positions where the ratio of wiper resistance to actual resistance is much higher.  This enables users to do schematic calculations based on an actual 1 percent value, instead of competitive solutions that have >±20 percent tolerance of the resistor string in addition to wiper resistance error.

The 2009 Product of the Year Awards were announced in the January 2010 issue of Electronic Products with a cover feature and a brief description of Intersil's ISL22317. Intersil's winning product appears on the Electronic Products’ website at:
