DESCRIPTION

The TAS5112A is a high-performance, integrated stereo

digital amplifier power stage designed to drive 6-

Ω

speakers at up to 50 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 90%,

reducing the size of both the power supplies and heatsinks

needed.

Overcurrent

protection,

overtemperature

protection, and undervoltage protection are built into the

TAS5112A, safeguarding the device and speakers against

fault conditions that could damage the system.
