DESCRIPTION  
High Performance:  
The PCM1800 is a low-cost, single-chip stereo  
analog-to-digital converter (ADC) with single-ended  
analog voltage inputs. The PCM1800 uses  
delta-sigma modulator with 64 times oversampling,  
including a digital decimation filter and a serial  
interface which supports both master and slave  
modes and four data formats. The PCM1800 is  
suitable for a wide variety of cost-sensitive consumer  
applications where good performance is required.  
THD+N: –88 dB (typical)  
SNR: 95 dB (typical)

Master/Slave Modes  
Four Data Formats  
The PCM1800 is fabricated using a highly advanced  
CMOS process and is available in a small 24-pin  
SSOP package.  
Sampling Rate: 4 kHz to 48 kHz  
System Clock: 256 fS, 384 fS, or 512 fS
