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.
