DESCRIPTION
The TAS5111A is a high-performance digital amplifier
power stage designed to drive a 4-
speaker up to 70 W
with 0.2% distortion plus noise. 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 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 TAS5111A, safeguarding the
device and speakers against fault conditions that could
damage the system.
