Xicor® Introduces Family of Sensor Conditioning Bias Controllers For Embedded Applications
-- Devices Allow for Automatic Output Compensation by Using Sensor Lookup Tables
MILPITAS, California June 24, 2003 Xicor, Inc. (Nasdaq: XICO), a leading supplier of analog mixed-signal integrated circuits, today unveiled three new Sensor Conditioning Bias Controllers, the X96010, X96011 and X96012. These devices are targeted at various applications that include PIN diode bias control, RFPA bias control, temperature compensated process control, laser diode bias control, fan control, motor control and a variety of sensor signal conditioning or data acquisition applications.
Each of the devices contain various combinations of the following functions: an 8-bit analog to digital converter (ADC), temperature sensor, voltage reference, 8-bit digital to analog converters (DAC), current output generators and nonvolatile lookup tables with datapath selection to either internal or external data converters. Register control of DAC full scale output, reference and sensor input selection and DAC sink or source mode enables versatility for signal conditioning applications.

These devices are ideal for applications in which the implementation of independent, non-linear compensation curves are used to automatically control programmable current sources. The programmable current source outputs can be used for sensor bias current, programmable voltage sources, electronic loads, amplifier gain and offset control, or function generators.
The Sensor Conditioning Bias Controllers provide innovative solutions that can be used to map complex conditions such as temperature, pressure, speed or position into digitally compensated curves that translate to an output current. The nonvolatile look-up tables can be programmed once or can be periodically modified to account for systematic errors and component variations. Once the compensation curves are defined and loaded into the lookup tables, the device can run independently without using a microcontroller, making the devices ideal for embedded applications, stated Tony Ochoa, product marketing manager.
These devices operate in extended temperature range from -40ºC to +100ºC and operating voltages from 3V to 5.5V. Production samples for the X96010, X96011 and X96012 are currently available in 14 pin TSSOP packaging with 1k unit prices starting at $2.40.
