DESCRIPTION
The TAS5111A is a high-performance digital amplifier power stage designed to drive a 4-Ω speaker up to 70 W with 0.2% distortion plus noise. The device incorporates TI’s Pure Path 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...
