TIDA-00874
具數位輸入和處理能力的高傳真 175W D 類音訊放大器參考設計
TIDA-00874
概覽
This design turns the extremely high performance analog input TPA3251 Class-D amplifier into a digital input system with audio processing using the highly versatile PCM5242 differential output DAC. Now the full performance of TPA3251 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 TPA3251 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.
特點
- High performance and audio fidelity from the TPA3251 with digital sources
- Accepts USB, Optical, SPDIF and I2S format digital inputs
- 175W @ 10% THD + N from digital sources
- Less than 0.004% THD + N 10W into 4ohms
- miniDSP processing flexibility with PCM5242 DAC
- Fully differential analog path for noise rejection
