DESCRIPTION  
The PCM1803A is high-performance, low-cost,  
single-chip stereo analog-to-digital converter with  
single-ended analog voltage input. The PCM1803A  
uses a delta-sigma modulator with 64- and 128-times  
oversampling, and includes a digital decimation filter  
and high-pass filter, which removes the dc  
component of the input signal. For various  
applications, the PCM1803A supports master and  
slave modes and four data formats in serial interface.  
The PCM1803A is suitable for a wide variety of  
cost-sensitive consumer applications where good  
performance and operation from a 5-V analog supply  
and 3.3-V digital supply are required. The  
PCM1803A is fabricated using a highly advanced  
CMOS process and is available in a small 20-pin  
SSOP package.  
– THD+N: –95 dB (Typically)  
– SNR: 103 dB (Typically)  
– Dynamic Range: 103 dB (Typically)  
PCM Audio Interface:  
– Master/Slave Mode Selectable  
– Data Formats:  
24-Bit Left-Justified  
24-Bit I2S  
20-, 24-Bit Right-Justified  
Sampling Rate: 16 kHz to 96 kHz  
System Clock: 256 fS, 384 fS, 512 fS, 768 fS  
Dual Power Supplies: 5 V for Analog, 3.3 V  
for Digital  
Package: 20-Pin SSOP
