DESCRIPTION
The TAS5121 is a high-performance digital amplifier
power stage designed to drive a 4-
speaker up to 100 W.
The device incorporates PurePath Digital
technology
and can be used with a TI audio PWM processor 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 TAS5121, safeguarding the
device and speakers against fault conditions that could
damage the system.
