IRVINE SENSORS ANNOUNCES 'SENSOR-ON-A-CHIP' PRODUCT

 COSTA MESA, Calif., June 2 /PRNewswire/ -- Irvine Sensors Corp. (NASDAQ: IRSN) unveiled a new product today, a device that can perform the functions of a complete sensor, all on a single integrated circuit chip less than a quarter of an inch on a side. The product is expected to have widespread applicability to both military and commercial infrared sensor systems. The new device, referred to by Irvine as a Dual Spectrum Digital Readout(TM), can read the signals from two different wavelength sensors simultaneously, amplify those signals, convert them from analog to digital form and provide various control features.
 An earlier version of the chip was developed by Irvine Senors under contract from the U.S. Navy's Air Warfare Center for potential use on advanced air-to-air missiles incorporating both radar and infrared homing devices. Such a dual-use feature is expected to be a key requirement for the follow-on to the Sidewinder missile, expected to be procured starting next year. Irvine's testing and enhancement of the Navy chip led to the product being announced today. Other anticipated applications include NASA measurement satellites, commercial and medical instrumentation and intrusion alarms integrating signals from different classes of sensors.
 The Dual Spectrum Digital Readout is immediately available in a configuration which can interact with 32, tunable long-wavelength infrared detectors or 16 long-wavelength detectors and, at the same time, 16 medium-wavelength detectors, all operating at cryogenic temperatures. This configuration operates at a 12.5 KHz sample rate, has a variable integration period ranging from 2 to 70 microseconds, has variable integration capacitors ranging from .5 to 10 picofarads, performs analog to digital conversion for 10 bit words and operates at only 100 milliwatts of power. It will be sold in either a bare die form or integrated into a 108 pin-grid array. Future configurations of the chip are planned by Irvine Sensors to interface with different types of detector arrays. The firm also offers to design and build custom chips incorporating cells from the Dual Spectrum Digital Readout or other elements from its extensive cell library. In addition, Irvine will integrate Dual Spectrum Digital Readout chips with infrared detector arrays.
 Irvine Sensors Corp., headquartered in Costa Mesa, is primarily engaged in the development of infrared devices and high-density packages of computer electronics which are intended to have broad applications in military and commercial systems.
