The TAS5122 is a high-performance, integrated stereo digital amplifier power stage designed to drive 6-Ω speakers at up to 30 W per channel. The device incorporates TI’s PurePath Digitalt technology and is used 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%. 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.
