Burr-Brown Introduces Six-Channel Audio DAC for DVD Applications.TUCSON, Ariz.--(BUSINESS WIRE)--Oct. 11, 1999-- Burr-Brown Corporation (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :BBRC) today announced the PCM1600, a high performance, six-channel audio DAC See D/A converter and discretionary access control. DAC - Digital to Analog Converter (digital-to-analog converter) featuring 24-bit resolution and 96kHz sampling rate for use in a wide variety of multi-channel audio applications such as DVD DVD: see digital versatile disc. DVD in full digital video disc or digital versatile disc Type of optical disc. The DVD represents the second generation of compact-disc (CD) technology. (Digital Versatile Disc digital versatile disc or digital video disc (DVD), a small plastic disc used for the storage of digital data. The successor media to the compact disc (CD), a DVD can have as much as 26 times the storage capacity of a CD. ). The PCM1600 contains six 24-bit, 96kHz, 105dB dynamic range audio DACs combined together on a single monolithic integrated circuit The common form of chip design, in which the base material (substrate) contains the pathways as well as the active elements that take part in its operation. . The device is optimized for DVD players, AV receivers, HDTV receivers, car audio systems, multi-channel home theater systems, surround-sound processors, and digital mixing consoles. "The integration, performance, and price offered by the PCM1600 is exactly what audio system designers have been waiting for," said Mike Centorino, audio product marketing manager at Burr-Brown. The PCM1600 utilizes Burr-Brown's proprietary "Enhanced Multi-Level Delta-Sigma" modulator technology to achieve excellent audio dynamic performance and reduced jitter sensitivity in actual applications. This highly integrated device features 105dB dynamic range and -96dB THD+N on each of its six channels. The internal digital filter operates at 8x oversampling Creating a more accurate digital representation of an analog signal. In order to work with real-world signals in the computer, analog signals are sampled some number of times per second (frequency) and converted into digital code. with two selectable roll-off performances: sharp roll-off or slow roll-off. The digital filter offers -82dB stopband A stopband is a band of frequencies, between specified limits, in which a circuit, such as a filter or telephone circuit, does not let signals through. Frequencies between the lower and upper limits are not transmitted. attenuation and +/-0.002dB passband pass·band n. The range of frequencies transmitted by a bandpass filter. ripple. Functions of the PCM1600 include digital attenuation, mute, and zero flag for each channel. The device accepts industry-standard audio data formats (16/18/20/24-bit audio data) and can be used with 256, 384, 512, or 768fs system clocks. The PCM1600 processes up to 24 bits internally and has single-ended analog outputs, thus reducing the amount of external components needed. It operates on dual +3.3V and +5V power supplies. The PCM1600 is priced from $8.95 in 1,000 piece quantities and is packaged in a 48-lead LQFP. Delivery is from stock.
