Tucson, Ariz.-- Dec. 22, 1997--Burr-Brown Corp.introduced the low-costPCM3002 and PCM3003 16/20-bit, single-chip stereo audio CODECs--analog-to-digital (ADC) and digital-to-analog (DAC) converters--offering3-V operation ideal for low-power portable applications.
PCM3002 and PCM3003's low cost, small package, and low-power operation make them the perfect choice for consumer portable and handheld systems. In addition, the PCM3002 and PCM3003 contain a unique power-down capability, which allows the designer to "disable" the internal ADC or DAC portions of the device individually--resulting in significant power savings.
Applications for the PCM3002 and PCM3003 include portable DAT (Digital Audio Tape) players, mini-disc players, and handheld test and measurement devices, as well as a wide variety of cost-sensitive consumer applications. According to Euromonitor's Strategy 2000 report, the world consumer electronics market will exceed $137 billion in sales in 1998.
PCM3002 and PCM3003 feature single-ended analog voltage input andoutput. The ADC and DAC cores employ delta-sigma modulation with 64(oversampling. The ADC also includes a digital decimation filter, while the DAC includes an 8( oversampling digital interpolation filter, digital attenuation, soft mute, and digital de-emphasis. Both are fabricated on a highly advanced 0.6-(m CMOS process and operate with left-justified, right-justified, or I2S data formats. PCM3002 and PCM3003 are packaged in a small 24-lead SSOP and priced from $6.95 in 1000s. Delivery is from stock.
