DESCRIPTION
The PCM1807 is high-performance, low-cost,
single-chip stereo analog-to-digital converter with
single-ended analog voltage input. The PCM1807
uses a delta-sigma modulator with 64-times
oversampling and includes a digital decimation filter
and high-pass filter that removes the dc component
of the input signal. For various applications, the
PCM1807 supports master and slave mode and two
data formats in serial audio interface.
The PCM1807 has many functions which are con-
trolled through SPI serial-control port: power down,
fade-in and fade-out, polarity control, etc.
The PCM1807 is suitable for wide variety of
cost-sensitive consumer applications where good per-
formance and operation with a 5-V analog supply and
3.3-V digital supply is required. The PCM1807 is
fabricated using a highly advanced CMOS process
and is available in a small, 14-pin TSSOP package.

This integrated circuit can be damaged by ESD. Texas Instruments 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.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
