The PCM3008 is a low cost single chip 16-bit stereo audio codec with single-ended analog voltage input and output.
Both ADCs and DACs employ delta-sigma modulation with 64-times oversampling. ADCs include a digital decimation filter and digital high pass filter. DACs include an 8-times oversampling digital interpolation filter, digital de-emphasis filter and pop-noise free muting which works during the power down ON/OFF sequence. The PCM3008 accepts left-justified format for ADC, and right-justified format for DAC. Independent power-down modes for ADC and DAC are provided.
The PCM3008 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.
