8-Channel DAC with PLL,  
192 kHz, 24 Bits  
AD1934  
FEATURES  
GENERAL DESCRIPTION  
PLL generated or direct master clock  
Low EMI design  
108 dB DAC dynamic range and SNR  
−94 dB THD + N  
The AD1934 is a high performance, single-chip that provides  
eight digital-to-analog converters (DACs) with single-ended  
output using the Analog Devices, Inc. patented multibit sigma-  
delta (Σ-Δ) architecture. An SPI port is included, allowing a  
microcontroller to adjust volume and many other parameters.  
The AD1934 operates from 3.3 V digital and analog supplies.  
The AD1934 is available in a 48-lead (single-ended output)  
LQFP. Other members of this family include a differential DAC  
output and I2C® control port version.  
Single 3.3 V supply  
Tolerance for 5 V logic inputs  
Supports 24 bits and 8 kHz to 192 kHz sample rates  
Single-ended DAC output  
Log volume control with autoramp function  
SPI® controllable for flexibility  
Software-controllable clickless mute  
Software power-down  
Right-justified, left-justified, I2S and TDM modes  
Master and slave modes up to 16-channel in/out  
48-lead LQFP  
The AD1934 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 the master clock from the  
LR clock or from an external crystal, the AD1934 eliminates the  
need for a separate high frequency master clock and can also be  
used with a suppressed bit clock. The digital-to-analog  
converters are designed using the latest ADI continuous time  
architectures to further minimize EMI. By using 3.3 V supplies,  
power consumption is minimized, further reducing emissions.
