APPLICATIONS

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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
