DESCRIPTION

The TAS5121 is a high-performance digital amplifier

power stage designed to drive a 4-鈩?speaker up to 100 W.

The device incorporates PurePath Digital錚?technology

and can be used with a TI audio 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 TAS5121, safeguarding the

device and speakers against fault conditions that could

damage the system.
