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

supportsmasterandslavemodesandfourdataformats

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.

High Performance

– THD+N: 96 dB (Typical)

– SNR: 105 dB (Typical)

– Dynamic Range: 105 dB (Typical)

PCM Audio Interface

– Master/Slave Mode Selectable

– Data Formats: 24-Bit Left-Justified;

24-Bit I S; 20-, 24-Bit Right-Justified

Sampling Rate: 16 kHz to 96 kHz

System Clock: 256 f , 384 f , 512 f , 768 f

Dual Power Supplies: 5 V for Analog, 3.3 V for

Digital

Package: 20-Pin SSOP

Lead-Free Product

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 V

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.

Other trademarks are the property of their respective owners.

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.
