DESCRIPTION  
The PCM1748 is a CMOS, monolithic, integrated  
circuit which includes stereo digital-to-analog con-  
verters (DAC) and support circuitry in a small  
SSOP-16 package. The data converters use Texas  
Instruments' enhanced multilevel delta-sigma archi-  
tecture that employs fourth-order noise shaping and  
8-level amplitude quantization to achieve excellent  
dynamic performance and improved tolerance to  
clock jitter. The PCM1748 accepts industry-standard  
audio data formats with 16- to 24-bit data, providing  
easy interfacing to audio DSP and decoder chips.  
Sampling rates up to 100 kHz are supported. A full  
set of user-programmable functions is accessible  
through a 3-wire serial-control port that supports  
register write functions.  
• 0.002%, Typical (PCM1748KE)  
• 0.003%, Typical (PCM1748E)  
– Full-Scale Output: 3.1 Vp-p, Typical  
8× Oversampling Digital Filter:  
– Stop-Band Attenuation: –55 dB  
– Pass-Band Ripple: ±0.03 dB  
Sampling Frequency: 5 kHz to 100 kHz
