The document describes the TAS5111, a high-performance digital amplifier power stage designed to drive a 4-Ω speaker with a maximum output power of 70W. The device utilizes TI's PurePath Digital technology and is used in conjunction with a digital audio PWM processor (TAS50XX) and a simple passive demodulation filter to achieve high-quality, high-efficiency digital audio amplification. The efficiency of this amplifier can exceed 90%, depending on the system design. The TAS5111 incorporates overcurrent protection, overtemperature protection, and undervoltage protection to safeguard the device and speakers against fault conditions that could damage the system.
The TAS5111 is a high-performance digital amplifier power stage designed to drive a 4-Ω speaker up to 70 W with less than 0.2% distortion plus noise. It incorporates TI's PurePath Digital™ technology and is intended for use with a digital audio PWM processor (TAS50XX) and a simple passive demodulation filter.
