TAS5122

50W 立体声数字放大器功率级

The is a high-performance, integrated stereo digital amplifier power stage designed to drive 6- speakers at up to 30 W per channel. The device incorporates ’s PurePath Digital™ technology and is used in conjunction with a digital audio PWM processor TAS50XX and a simple passive demodulation filter to deliver high-quality, high-efficiency, true-digital audio amplification.

The efficiency of this digital amplifier is typically greater than 90%, reducing the size of both the power supplies and heat sinks needed. Overcurrent protection, overtemperature protection, and undervoltage protection are built into the TAS5122, safeguarding the device and speakers against fault conditions that could damage the system.
