DESCRIPTION
The TAS5112A is a high-performance, integrated stereo
digital amplifier power stage designed to drive 6-
speakers at up to 50 W per channel. The device
incorporates TI’s PurePath Digital 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,
protection, and undervoltage protection are built into the
TAS5112A, safeguarding the device and speakers against
fault conditions that could damage the system.
