DESCRIPTION
PCM1800 is a low cost, single chip stereo analog-todigital converter with single-ended analog voltage inputs. The PCM1800 uses a delta-sigma modulator with 64X oversampling, including a digital decimation filter and serial interface which supports both Master and Slave Modes and four data formats. PCM1800 is suitable for a wide variety of cost-sensitive consumer applications where high performance is required. PCM1800 is fabricated on a highly advanced CMOS process.

ELECTROSTATIC 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.
ABSOLUTE MAXIMUM RATINGS
