DESCRIPTION

The TAS5122 is a high-performance, integrated stereo

digital amplifier power stage designed to drive 6-

Ω

speakers at up to 30 W per channel. The device

incorporates TI’s PurePath Digital

t 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.
