DESCRIPTION
The PCM3000/3001 is a low cost single chip stereo
audio CODEC (analog-to-digital and digital-to-analog
converter) with single-ended analog voltage input and
output.
Both 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. The PCM3000/3001 operates with leftjustified, right-justified, I2S or DSP data formats.
PCM3000 can be programmed with a 3-wire serial
interface for special features and data formats.
PCM3001 can be pin-programmed for data formats.
Fabricated on a highly advanced CMOS process, the
PCM3000/3001 is suitable for a wide variety of costsensitive consumer applications where good performance is required. Applications include sampling keyboards, digital mixers, mini-disc recorders, hard-disk
recorders, karaoke systems, DSP-based car stereo,
DAT recorders, and video conferencing.

DISCHARGE SENSITIVITY
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
parametric changes could cause the device not to meet its
published specifications.
