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, right-justified, or I2S data formats.
PCM3002 and PCM3003 provide a power-down mode
that operates on the ADCs and DACs independently.
Fabricated on a highly advanced 0.6ms CMOS process,
PCM3002 and PCM3003 are suitable for a wide
variety of cost-sensitive consumer applications where
good performance is required.
PCM3002’s multi-functions are controlled by software
and the PCM3003’s functions include de-emphasis,
power down, and audio data format selections,
which are controlled by hardware.
