PCM1801 is a low cost, single chip stereo analog-to-
digital converter with single-ended analog voltage
inputs. The PCM1801 uses a delta-sigma modulator
with 64x oversampling, a digital decimation filter, and
a serial interface which supports Slave mode operation
and two data formats. The PCM1801 is suitable for a
wide variety of cost-sensitive consumer applications
where good performance is required.

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.
