Dual CMOS 18-Bit Monolithic Audio  
ANALOG-TO-DIGITAL CONVERTER  
FEATURES  
DESCRIPTION  
DUAL 18-BIT LOW-POWER CMOS AUDIO  
The PCM1750 is a low cost, dual 18-bit CMOS  
analog-to-digital converter optimized for dynamic sig-  
nal applications. The PCM1750 features true co-phased  
inputs with an internal sample/hold function for each  
channel. The PCM1750 also comes complete with an  
internal reference. Total power dissipation is less than  
300mW max using ±5V voltage supplies. Low maxi-  
mum Total Harmonic Distortion + Noise (–88dB max)  
is 100% tested. The very fast PCM1750 is capable  
of 4X x audio bandwidth oversampling rates on both  
input channels simultaneously, providing greater free-  
dom to designers in selecting input anti-aliasing fil-  
ters.
