PRODUCT OVERVIEW  
The AD1953 is a complete 26-bit, single-chip, 3-channel digital  
audio playback system with built-in DSP functionality for speaker  
equalization, dual-band compression/limiting, delay compensa-  
tion, and image enhancement. These algorithms can be used to  
compensate for real-world limitations of speakers, amplifiers,  
and listening environments, resulting in a dramatic improvement  
of perceived audio quality.  
2 Control Registers Allow Complete Control of Modes  
and Memory Transfers  
Differential Output for Optimum Performance  
112 dB Signal-to-Noise (Not Muted) at 48 kHz Sample  
Rate (A-Weighted Stereo)  
70 dB Stop-Band Attenuation  
On-Chip Clickless Volume Control  
Hardware and Software Controllable Clickless Mute  
Digital De-emphasis Processing for 32 kHz, 44.1 kHz, 48 kHz  
Sample Rates  
The signal processing used in the AD1953 is comparable to that  
found in high end studio equipment. Most of the processing is  
done in full 48-bit double-precision mode, resulting in very good  
low level signal performance and the absence of limit cycles or  
idle tones. The compressor/limiter uses a sophisticated two-band  
algorithm often found in high end broadcast compressors.
