Burr-Brown Unveils Low Cost, High Speed ADCs for Imaging Systems.

TUCSON, Ariz.--(BUSINESS WIRE)--June 10, 1998--Burr-Brown Corporation (NASDAQ:BBRC) today announced the low cost ADS830 and ADS831 high speed analog-to-digital converters (ADCs) offering high signal-to-noise ratio (improved signal quality), low power operation (less heat dissipation and longer battery life), and the industry's highest number of effective bits for an 8-bit ADC (near-ideal performance) in a small 20-pin package.

High signal-to-noise ratio (SNR) and low distortion provide the extra performance margin which makes these products especially suited for imaging applications including medical imaging, LCD (Liquid Crystal Display) video projection, and scanners.

In an ultrasound receiver application, the ADS830 converts analog signals of the ultrasound echo, at a rate of 60-80 million signals per second, to digital signals. This high conversion rate enhances the quality of reconstructed images shown on the display. The ADS830's low cost and small size make it attractive to ultrasound system designers who are increasing the number of image processing channels in their products in order to further improve the image quality.

Patrick Kirk, strategic marketing manager at Burr-Brown, said: "These products are not only a unique breakthrough in that they achieve high SNR while requiring very low power, but they provide this performance for under $4.00. Cost reduction and low power operation are important to the designer of an ultrasound system since there are hundreds of channels per system."

According to IC Insights' "The McClean Report -- 1998 Edition," the worldwide market for analog-to-digital converter integrated circuits (ICs) will exceed $880 million in 1998 and grow to over $1.3 billion in year 2001.

The ADS830 and ADS831 include an 8-bit quantizer and feature 49dB SNR (signal-to-noise ratio), internal/external reference option, single-ended or differential analog input, 1Vp-p/2Vp-p programmable input range, high bandwidth track/hold, and single +5V supply operation. They offer low power dissipation (ADS830 = 170mW, ADS831 = 275mW) and provide a power-down mode to reduce power dissipation to 20mW. unications, industrial control, instrumentation, consumer electronics, and personal computer systems.
