DESCRIPTION
The PCM1804 is a high-performance single chip stereo
A/D converter with full differential analog voltage input.
The PCM1804 uses a precision delta-sigma modulator
and includes a linear phase antialias digital filter and
HPF (low-cut filter) that removes dc offset of the input
signal. The PCM1804 is suitable for a wide variety of
mid-to-high grade consumer and professional
applications, where excellent performance and 5-V
analog supply and 3.3-V digital power supply operation
are required. The PCM1804 can achieve both PCM
audio and DSD format due to precision delta-sigma
modulator. The PCM1804 is fabricated on an advanced
CMOS process and is available in small 28-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 available from Texas Instruments.
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.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
