PCM3008T

Product Summary

The PCM3008T is a low cost single chip 16-bit stereo audio codec with single-ended analog voltage input and output. The PCM3008T accepts left-justified format for ADC, and right-justified format for DAC. Independent power-down modes for ADC and DAC are provided. The PPCM3008T is suitable for a wide variety of cost-sensitive consumer applications where good performance is required. It is fabricated using a highly advanced CMOS process and is available in a small 16-pin TSSOP package. The applications of the PCM3008T include Digital Video Camera, Portable MD Player and Other Portable System.
