4 ADC/8 DAC with PLL,  
192 kHz, 24 Bit CODEC  
Preliminary Technical Data  
AD1935/AD1936/AD1937/AD1938/AD1939  
Features  
Applications  
PLL generated (32-192kHz) or direct master clock  
Low EMI design  
109 dB DAC/ 107dB ADC Dynamic Range and SNR  
-94dB THD+N  
Automotive audio systems  
Home theater systems

Digital audio effects processors  
Single 3.3V Supply  
Tolerance for 5V logic inputs  
GENERAL DESCRIPTION  
Supports 24-bits and 8 kHz - 192 kHz sample rates  
Differential ADC input  
The AD193X family are high performance, single-chip codecs that  
provide 4 ADCs with differential input and 8 DACs with either  
single-ended or differential output using ADIs patented multibit  
sigma-delta architecture. An SPI® or I2C® port is included, allowing  
a microcontroller to adjust volume and many other parameters.  
The AD193X family operates from 3.3V digital and analog supplies.  
The AD193X is available in a 48-lead (SE output) or 64-lead  
(differential output) LQFP package.  
Single-ended or Differential DAC output versions  
Log volume control with "auto-ramp" function  
Hardware and software controllable clickless mute  
Software and hardware power-down  
Right justified, left justified, I2S and TDM Modes  
Master and slave modes up to 16 channel in/out  
48-lead LQFP or 64-lead LQFP plastic package  
The AD193X is designed for low EMI. This consideration is  
apparent in both the system and circuit design architectures. By  
using the on-board PLL to derive master clock from L-R clock, the  
AD193X eliminates the need for a separate high frequency master  
clock. It can also be used with a suppressed bit clock. The D-A and  
A-D converters are designed using the latest ADI continuous time  
architectures to further minimize EMI. By using 3.3V supplies,  
power consumption is minimized, further reducing emissions.
