DESCRIPTION  
•
Zero Flags for Selectable Channel  
Combinations  
The PCM1680 is a CMOS monolithic integrated  
circuit which features eight 24-bit audio digi-  
tal-to-analog converters and support circuitry in a  
small 28-lead SSOP. The digital-to-analog converters  
use TI's enhanced multilevel delta-sigma architecture  
to achieve excellent signal-to-noise performance and  
a high tolerance to clock jitter.  
•
•
Serial Port (SPI/I2C) for Mode Control  
User-Programmable Functions:  
– Flexible Audio Data Formats  
• Right-Justified, I2S, and Left-Justified  
• 16-, 18-, 20-, and 24-Bit Audio Data  
– Digital Attenuation: Mode Selectable  
• 0 dB to –63 dB, 0.5 dB/step  
• 0 dB to –100 dB, 1 dB/step  
– Soft Mute  
The PCM1680 accepts industry-standard audio data  
formats with 16- to 24-bit audio data. Sampling rates  
up to 200 kHz are supported. The PCM1680 provides  
a full set of user-programmable functions through a  
serial control port, SPI or I2C.  
– Digital De-Emphasis  
– Digital Filter Rolloff: Sharp or Slow
