DESCRIPTION

Software Control (PCM1753, PCM1755):  
The PCM1753/54/55 is a CMOS, monolithic, integrated  
circuit, which includes stereo digital-to-analog converters  
and support circuitry in a small 16-lead SSOP package.  
The data converters use TI’s enhanced multilevel  
delta-sigma architecture, which employs 4th-order noise  
shaping and 8-level amplitude quantization to achieve  
excellent dynamic performance and improved tolerance to  
clock jitter. The PCM1753/54/55 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 200 kHz are supported. A full  
set of user-programmable functions is accessible through  
a three-wire serial control port, which supports register  
write functions.  
Accepts 16-, 18-, 20-, and 24-Bit Audio

Formats: Standard, I S, and Left-Justified  
Digital Attenuation: 0 dB to –63 dB,  
0.5 dB/Step

Digital Filter Rolloff: Sharp or Slow  
Soft Mute  
Zero Flags for Each Output  
Open-Drain Output Zero Flag (PCM1755)

Output  
The PCM1753/55 is pin compatible with the PCM1748,  
PCM1742, and PCM1741, except for pin 5.  
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during  
storage or handling to prevent electrostatic damage to the MOS gates.
