(1) Stresses beyond those listed under "absolute maximum ratings"may cause permanent damage to the device. These are stress atings only, and functional operation of the device at these or any ther conditions beyond those indicated under "recommendedoperating conditions" is not implied. Exposure to absolutemaximum-rated conditions for extended periods may affect device eliability.
(2) GREG is treated as an input when the GREG pin is overdriven by VDD of 12 V.
DescriptionThe TAS5122 is a high-performance, integrated stereo igital amplifier power stage designed to drive 6- speakers at up to 30 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 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.
