DESCRIPTION
The PCM1802 is a high-performance, low-cost,
single-chip stereo analog-to-digital converter with
single-ended analog voltage input. The PCM1802 uses
a delta-sigma modulator with 64- or 128-times over-
sampling, and includes a digital decimation filter and
HPF (low cut filter) which removes the dc component of
the input signal. For various applications, the PCM1802
supports master and slave modes and four data formats
in serial interface. The PCM1802 is suitable for a wide
variety of cost-sensitive consumer applications where
good performance, 5-V analog supply, and 3.3-V digital
supply operation is required. The PCM1802 is
fabricated using a highly advanced CMOS process and
is available in the DB 20-pin SSOP package.
This device contains circuits to protect its inputs and outputs against damage due to high static voltages or electrostatic fields. These
circuits have been qualified to protect this device against electrostatic discharges (ESD) of up to 2 kV according to MIL-STD-883C,
Method 3015; however, it is advised that precautions be taken to avoid application of any voltage higher than maximum-rated
voltages to these high-impedance circuits. During storage or handling, the device leads should be shorted together or the device
should be placed in conductive foam. In a circuit, unused inputs should always be connected to an appropriated logic voltage level,
preferably either VCC or ground. Specific guidelines for handling devices of this type are contained in the publication
Guidelines for
Handling Electrostatic-Discharge-Sensitive (ESDS) Devices and Assemblies

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
