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.
