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