AD1953YSTZ, SigmaDSP Digital Audio Processor, 48 Pin LQFP, Quantity 2, Analog Devices.
The AD1953 is a complete, 26-bit, single-chip, 3-channel digital audio playback system with built-in DSP functionality. Key features include: 3 channels of digital audio, 6-channel TDM output mode, a 7-band, 48-bit stereo equalizer, delays for loudspeaker location adjustment, Phat Stereo spatial enhancement, and a dual-band, professional-quality dynamics processor. Its three DACs achieve 112 dB signal-to-noise ratio (SNR) at 48 kHz. Its dynamic processing features include:
* Finely-tuned bass boost to enhance low frequencies for small loudspeakers
* Algorithms that virtually increase loudness by removing distortion at high volumes
* Midnight mode which automatically reduces loudness in high-volume instances (e.g., sudden loud scenes on DVDs)
* Low-level expansion to lift low-volume signals above road noise (for car stereos)
* 5 V 3-Channel Audio DAC System
* Digital Audio Output (2-Channel or 6-Channel Packed Mode)
* Accepts Sample Rates up to 48 kHz
* 7 Biquad Filter Sections per Channel
* Dual Dynamic Processor with Arbitrary Input/Output
* Curve and Adjustable Time Constants
* 0 ms to 6 ms Variable Delay/Channel for Speaker Alignment
* 2.0/2.1 Channel Audio Systems (2 Main Channels Plus Subwoofer)
* Multichannel Automotive Sound Systems
* Home Theater Systems (AC-3 Postprocessor)
* In-Seat Sound Systems (Aircraft, Motor Coaches)
