The PCM3006 is a low cost single chip stereo audio CODEC (analog-to-digital and digital-to-analog con-verters) with single-ended analog voltage input and output.

Both ADCs and DACs PCM3006 employ delta-sigma modula-tion with 64X oversampling. The ADCs include a digital decimation filter, and the DACs include an 8X oversampling digital interpolation filter. The DACs also include a de-emphasis function. PCM3006 oper-ates with 16-bit, left-justified for ADC, right-justified for DAC data formats.

PCM3006 provides a Power-Down Mode that oper-ates on the ADCs and DACs independently.

Fabricated on a highly advanced 0.6s CMOS pro-cess, PCM3006 is suitable for a wide variety of cost-sensitive consumer applications where good performance is required. Applications of PCM3006 include sam-pling keyboards, digital mixers, effects processors, hard-disk recorders, data recorders and digital video cameras.
