DESCRIPTION

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.
