DESCRIPTION
The PCM1808-Q1 is high-performance, low-cost,
single-chip, stereo analog-to-digital converter with
single-ended analog voltage input. The PCM1808-Q1
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
PCM1808-Q1 supports master and slave mode and
two data formats in serial audio interface.
The PCM1808-Q1 supports the power-down and
reset function by means of halting the system clock.
The PCM1808-Q1 is suitable for wide variety of cost-
sensitive consumer applications where good
performance and operation with a 5-V analog supply
and 3.3-V digital supply is required. The PCM1808-
Q1 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.
