DESCRIPTION
The PCM3002 and PCM3003 are low cost single chip
stereo audio CODECs (analog-to-digital and digital-toanalog converters) with single-ended analog voltage
input and output.
The ADCs and DACs employ delta-sigma modulation
with 64X oversampling. The ADCs include a digital
decimation filter, and the DACs include an 8X
oversampling digital interpolation filter. The DACs
also include digital attenuation, de-emphasis, infinite
zero detection and soft mute to form a complete
subsystem. PCM3002 and PCM3003 operate with
left-justified, and right-justified formats, while the
PCM3002 also supports the I2S data format.
PCM3002 and PCM3003 provide a power-down mode
that operates on the ADCs and DACs independently.
Fabricated on a highly advanced CMOS process,
PCM3002 and PCM3003 are suitable for a wide variety of cost-sensitive consumer applications where good
performance is required.
PCM3002’s programmable functions are controlled
by software and the PCM3003’s functions include deemphasis, power down, and audio data format selections, which are controlled by hardware.

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
