DESCRIPTION
The PCM3002 and PCM3003 are low cost single chip
stereo audio CODECs (analog-to-digital and digital-to-
analog 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 I
2
S 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 vari-
ety of cost-sensitive consumer applications where good
performance is required.
PCM3002’s programmable functions are controlled
by software and the PCM3003’s functions include de-
emphasis, power down, and audio data format selec-
tions, which are controlled by hardware.
