DESCRIPTION

The TAS5111 is a high-performance digital amplifier power

stage designed to drive a 4-鈩?speaker up to 70 W with

0.2% distortion plus noise. The device incorporates TI鈥檚

PurePath Digital錚?technology and is used with a digital

audio PWM processor (TAS50XX) 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 TAS5111, safeguarding the

device and speakers against fault conditions that could

damage the system.
