The TAS5121I is a high-performance, digital-amplifier power stage designed to drive a 4- speaker up to 100 W. The TAS5121I is rated for operation at industrial temperatures. The device incorporates PurePath Digital™ technology and can be used with a TI audio pulse-width modulation (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 TAS5121I, safeguarding the device and speakers against fault conditions that could damage the system.
