FEATURES  
COMPLETE STEREO DAC: Includes Digital  
DESCRIPTION  
The PCM1744 is a complete low cost stereo audio  
digital-to-analog converter (DAC), operating off of a  
256fS or 384fS system clock. The DAC contains a 3rd-  
order ∆Σ modulator, a digital interpolation filter, and  
an analog output amplifier. The PCM1744 accepts  
24-bit input data in a I2S format.  
Filter and Output Amp  
DYNAMIC RANGE: 95dB  
MULTIPLE SAMPLING FREQUENCIES:  
Up to 96kHz

SYSTEM CLOCK: 256fS /384fS  
24-BIT I2S DATA INPUT FORMAT  
SMALL 14-PIN SOIC PACKAGE  
The digital filter performs an 8x interpolation function  
and includes de-emphasis at 44.1kHz. The PCM1744  
can accept digital audio sampling frequencies from  
16kHz to 96kHz, always at 8X oversampling.  
The PCM1744 is ideal for low-cost, CD-quality con-  
sumer audio applications.
