The TAS5112 is a high-performance, integrated stereo digital amplifier power stage designed to drive 6- speakers at up to 50 W per channel. The device incorporates TI's PurePath Digital 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 90%, reducing the size of both the power supplies and heatsinks needed. Overcurrent protection, overtemperature protection, and undervoltage protection are built into the TAS5112, safeguarding the device and speakers against fault conditions that could damage the system.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolutemaximum- rated conditions for extended periods may affect device reliability.
(2) The duration of voltage spike should be less than 100 ns.
(3) GREG is treated as an input when the GREG pin is overdriven by GVDD of 12 V.
