Xicor® Introduces Three Terminal Additions to the Non-Volatile 32-Tap Digitally Controlled Potentiometer Family
-- X93156 and X93256 create new standards in performance and integration while maintaining small form factor, low power and low pricing
MILPITAS, California June 7, 2004 Xicor, Inc. (NASDAQ: XICO), a leading supplier of high performance analog and mixed-signal integrated circuits, today announced a family of non-volatile linear taper 32-tap digitally controlled potentiometers (DCPs) with the introduction of the X93156 and X93256.
The X93156 and X93256 offer ultra low power single and dual DCPs at a highly competitive price to address new market needs for high volume and space constrained applications. The dual DCPs in the X93256 feature a three terminal, 32-tap wiper with an independent up/down interface. Along with ultra low power dissipation and supply voltage limits from 2.7V to 5V, the X93156 and X93256 also achieve less than ± 0.2 least significant bit (LSB) typical differential non- linearity (DNL).
By being digitally adjustable, these devices can help customers prevent stability issues due to vibration or shock in their systems commonly associated with mechanical potentiometers. In addition, unlike onetime programmable or volatile solutions, the X93156 and X93256 integrate non- volatile memory for the wiper position to eliminate additional high voltage supplies required by one-time programmable products.
The simple up/down interface can be used for personalized environments such as LCD contrast and backlight brightness control in cell phones, PDAs and GPS receivers. The integration of reprogrammable solid-state potentiometers with an up/down interface is important in systems requiring multiple gains, reference voltage and bias calibrations such as common mode amplifier biasing and feedback gain adjustments. Other target applications include process controls requiring parameter retention and data acquisition systems requiring preconfigured reference voltage levels.
Offering a robust portfolio of 32-tap DCPs and offering an option in terminal choices was a natural move for Xicor, stated Anthony Mercado, product marketing engineer. With the new X93156 and X93256, Xicor is further broadening its DCP line to provide designers with high performance, low power, competitively priced DCPs that they can continue to use well into the future.
Production samples are available in 8-pin MSOP (single) and 14-pin TSSOP (dual) packaging with 1k unit prices starting at $0.56 USD for the single and $0.95 USD for the dual.
