Stereo Audio  
DIGITAL-TO-ANALOG CONVERTER  
FEATURES  
DESCRIPTION  
16-BIT RESOLUTION  
The PCM1712 is a complete low cost stereo, audio  
digital-to-analog converter, including digital interpo-  
lation filter, 3rd-order delta-sigma DAC, and analog  
output amplifiers. PCM1712 accepts 16-bit normal  
input data (MSB first, right justified), or 16-bit IIS  
data (32-bits per word, continuous clock).  
COMPLETE STEREO DAC:  
8X Oversampling Digital Filter  
Multi-Level Delta-Sigma DAC  
Analog Low Pass Filter  
Output Amplifier  
The digital filter performs an 8X interpolation func-  
tion, as well as special functions such as soft mute,  
digital attenuation, de-emphasis and double-speed  
dubbing.  
HIGH PERFORMANCE:  
–87dB THD + N  
94dB Dynamic Range  
98dB SNR  
PCM1712 is suitable for a wide variety of cost-sensi-  
tive consumer applications where good performance is  
required. Its low cost, small size and single +5V power  
supply make it ideal for automotive CD players, book-  
shelf CD players, BS tuners, keyboards, MPEG audio,  
MIDI applications, set-top boxes, CD-ROM drives,  
CD-Interactive and CD-Karaoke systems. PCM1712  
has the same pinout functions as PCM1710.
