Car Audio-amp Has Digital Input

摘要

The TDA7801 digital-input audio-amplifier addresses the trend toward a fully digital head unit and sound systems in the car. Direct connec- tion to the digital audio player eliminates the need for signal conver- sion, resulting in higher sound quality, better noise immunity, simpler system design and greater system reliability. The part offers an SNR from around 90 to more than 105 dB and delivers intrinsically pop-free operation without clicks or noises during car battery transitions. In addition, the device comes complete with the most advanced built-in diagnostic features.
