Burr-Brown Introduces 24-Bit, 192kHz DAC for Consumer Audio Applications
Burr-Brown Corporation (NASDAQ: BBRC) has announced the PCM1737, a 24-bit, 192kHz sampling delta-sigma digital-to-analog converter (DAC) designed for consumer audio applications. The PCM1737's excellent price and performance is specifically targeted toward consumer audio applications such as DVD/CD players, A/V receivers, HDTV systems, and car audio applications. ""The PCM1737 is our first 192kHz delta-sigma audio DAC,"" said Mike Centorino, Audio Product Marketing Manager at Burr-Brown. ""The price/performance of this device makes it ideal for new systems which will support the emerging 192kHz DVD audio standard."" The device contains Burr-Brown's proprietary ""Enhanced Multi-Level Delta-Sigma"" modulator which improves audio dynamic performance and reduces jitter sensitivity. Special functions include digital attenuation, mute, and zero flag for each channel. The device accepts 16 to 24-bit input data and can be used with a variety of audio clocks. It processes up to 24 bits internally and has single ended analog outputs, thus reducing the amount of external components required in the audio system. It operates on dual power supplies (+3V digital and +5V analog) and is packaged in a small 28-lead SSOP. The PCM1737 is priced from $4.15 in 1,000 piece quantities. Delivery is from stock. A hardware-controlled version, the PCM1739, is also available with the same performance, packaging, supply voltage, and price as the PCM1737.
