TIDA-00874, High Fidelity 175W Class-D Audio Amplifier with Digital Inputs and Processing Reference Design

TIDA-00874, High Fidelity 175W Class-D Audio Amplifier with Digital Inputs and Processing Reference Design. This design turns the extremely high performance analog input TPA3251D2 Class-D amplifier into a digital input system with audio processing using the highly versatile PCM5242 differential output DAC. Now the full performance of TPA3251D2 amplifier can be realized with a variety of digital input sources. The analog differential output and high SNR of the PCM5242 DAC is a perfect match to the fully differential analog input of the TPA3251D2 amplifier achieving outstanding noise performance and extremely low distortion. With the miniDSP on the PCM5242, audio processing and filtering can be added to further enhance audio performance in the end equipment
