DESCRIPTION  
Sampling Frequency:  
The PCM1602A is a CMOS, monolithic integrated  
circuit that features six 24-bit audio digital-to-analog  
converters (DACs) and support circuitry in a small  
LQFP-48 package. The DACs use Texas Instruments'  
enhanced multilevel, delta-sigma architecture that  
employs fourth-order noise shaping and 8-level  
5 kHz to 200 kHz (Channels 1 and 2)  
5 kHz to 100 kHz (Channels 3, 4, 5, and 6)  
Accepts 16-, 18-, 20-, and 24-Bit Audio Data  
Data Formats: Standard, I2S™, and  
Left-Justified  
amplitude  
quantization  
to  
achieve  
excellent  
signal-to-noise performance and a high tolerance to  
clock jitter.  
System Clock: 128 fS, 192 fS, 256 fS, 384 fS, 512  
fS, or 768 fS  
The PCM1602A accepts industry-standard audio data  
formats with 16- to 24-bit audio data. Sampling rates  
up to 200 kHz (channels 1 and 2) or 100 kHz  
(channels 3, 4, 5, and 6) are supported. A full set of  
user-programmable functions is accessible through a  
4-wire serial control port that supports register write  
and read functions.  
User-Programmable Functions:  
Digital Attenuation: 0 dB to –63 dB,  
0.5 dB/Step  
Soft Mute  
Zero Flags Can Be Used As General-  
Purpose Logic Output  
Digital De-Emphasis  
Digital Filter Rolloff: Sharp or Slow  
Dual-Supply Operation:  
5-V Analog  
3.3-V Digital  
5-V Tolerant Digital Logic Inputs  
Package: LQFP-48
