Product Summary

The AD1940YSTZ is a complete 28-bit, single-chip, multichannel audio DSP for equalization, multiband dynamics processing, delay compensation, speaker compensation, and image enhancement. These algorithms can be used to compensate for the real-world limitations of speakers, amplifiers, and listening environments, resulting in a dramatic improvement of perceived audio quality. The applications of the AD1940YSTZ include Automotive sound systems Digital televisions, Home theater systems (Dolby Digital/DTS postprocessor), Multichannel audio systems, Mini-component stereos, Multimedia audio, Digital speaker crossover, Musical instrument, In-seat sound systems (aircrafts/motor coaches).
