Xicor Expands Its High Voltage Digital Potentiometer Portfolio X9319 Family; New 100-tap High Voltage Digital Pot.Business Editors/High-Tech Writers MILPITAS, Calif.--(BUSINESS WIRE)--July 28, 2003 Xicor(R), Inc. (Nasdaq:XICO), a leading supplier of high performance analog and mixed-signal integrated circuits A mixed-signal integrated circuit combines analog circuits with digital signal processing (DSP) circuits on a single semiconductor die. An integrated circuit that includes both analog and digital circuitry (but no DSP), like a 555 timer, is generally not considered a mixed-signal , today announced the X9319 family of 100-tap non-volatile digitally controlled potentiometers to expand its current digital potentiometer product line. The X9319 terminal voltages accommodate a voltage swing between 0V and 10V for an increased dynamic range and is well-suited for applications including offset and bias voltage See bias. adjustments in high voltage The term high voltage characterizes electrical circuits, in which the voltage used is the cause of particular safety concerns and insulation requirements. High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to amplifier and regulator designs. The X9319 family of potentiometers features 100-taps with 99-segmented resistors and is available in 10kohms and 50kohms total resistance options. Adjustments to the wiper position are made using a simple Up/Down interface and the position can be stored in the internal EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. for recall during device power-up. By utilizing the on-chip EEPROM, system designers lower cost by eliminating the need for an initializing microcontroller in their solution. The Up/Down interface allows efficient wiper position calibration for reduced manufacturing cost in bias and control applications. The programmability of the X9319 is a key component in high voltage systems requiring gain, reference voltage and bias calibrations such as common mode biasing in RF power amplifiers An RF power amplifier is a type of electronic amplifier used to convert a low-power radio-frequency signal into a larger signal of significant power, typically for driving the antenna of a transmitter. and gain adjustments in audio applications. Other target applications include signal-conditioning circuits to set zero offset and span correction for sensors, adjustments in process controls requiring parameter retention and data acquisition systems requiring pre-configured reference voltage levels. "Many commercial and industrial applications require the flexibility of a potentiometer with an increased voltage capability," stated Tony Ochoa, product marketing manager. "The X9319 is a cost-effective solution to accommodate high voltage supply applications." Xicor will be offering an evaluation kit and software support for this product. Production samples are available in 8-lead SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward.
