DESCRIPTION  
The PCM1780/81/82 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  
to achieve excellent dynamic performance and  
System Clock: 128 fS, 192 fS, 256 fS, 384 fS,  
512 fS, 768 fS, 1152 fS With Autodetect  
•
Software Control (PCM1780, PCM1782):  
– Accepts 16-, 18-, 20-, and 24-Bit Audio Data  
– Formats: Right-Justified, I2S, and  
Left-Justified  
improved  
tolerance  
to  
clock  
jitter.  
The  
PCM1780/81/82 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. The  
– Digital Attenuation: Mode Selectable  
• 0 dB to –63 dB, 0.5 dB/step  
• 0 dB to –100 dB, 1 dB/step  
– Digital De-Emphasis  
PCM1780/82  
provides  
a
full  
set  
of  
user-programmable functions through a three-wire  
serial control port, which supports register write  
functions. The PCM1781 provides a subset of  
user-programmable functions through four control  
pins.  
– Digital Filter Rolloff: Sharp or Slow  
– Soft Mute  
– Zero Flags for Each Output  
– Open-Drain Output Zero Flag (PCM1782)  
Hardware Control (PCM1781):  
– I2S and 16-Bit Word, Right-Justified  
– Digital De-Emphasis  
The PCM1780 is pin-compatible with the PCM1680  
(8-channel DAC).  
•
– Soft Mute  
– Zero Flag for L-, R-Channel Common  
Output  
•

•
Power Supply: 5-V Single Supply  
Small, 16-Lead SSOP Package (150 mil)  
Pin-Compatible with PCM1680
