TAS5121 100W 单声道数字放大器功率级

The TAS5121 is a high-performance digital amplifier power stage designed to drive a 4 speaker up to 100 W. The device incorporates PurePath Digital™ technology and can be used in conjunction with a TI audio PWM processor and a simple passive demodulation filter to deliver high-quality, high-efficiency digital audio amplification.

The efficiency of this digital amplifier can be greater than 90%, depending on the system design. Overcurrent protection, overtemperature protection, and undervoltage protection are built into the TAS5121, safeguarding the device and speakers against fault conditions that could damage the system.
