Business Wire, August 26, 1999

TUCSON, Ariz.--(BUSINESS WIRE)--Aug. 26, 1999--

Burr-Brown Corporation (NASDAQ: BBRC) today announced the development of the DSD1700, the Company's first Direct Stream Digital (DSD) audio digital-to-analog converter (DAC) designed for Sony's DSD technology which is used in Super Audio CD players, professional DSD processors, and DSD mixing consoles.

The DSD1700 is designed using Burr-Brown's high performance audio DAC technology under technical consultation by Sony Corporation for DSD technology. The device will directly convert 1-bit, 2.8224MHz digitally sampled data (the basic technology of Super Audio CD) to an analog signal.

"We are excited to work with Sony to produce our first DSD audio DAC for Super Audio CD," said Mike Centorino, audio product marketing manager at Burr-Brown. "The DSD1700, in combination with Sony's DSD decoder, will allow the user to achieve the high performance and sound quality associated with the Direct Stream Digital technology."

The DSD1700 is a single-channel DAC that will consist of a double differential analog FIR (Finite Impulse Response) filter. It will feature a wide frequency range up to 100kHz and more than 110dB signal-to-noise ratio (SNR).

The DSD1700 will directly interface to a DSD decoder and operate on a system clock of 11.2896MHz (256fs). The device will be packaged in a small 28-lead SSOP and operate on a single 5V power supply.

The DSD1700 is targeted to be priced at $9.95 in 1,000 piece quantities, with samples available later this year.
