Product Summary

The TAS5112DFD is a high-performance, integrated stereo digital amplifier. It is designed to drive 6Ω speakers at up to 50 W per channel. The TAS5112DFD is used with a digital audio PWM processor and a simple passive demodulation filter to deliver high-quality, high-efficiency, true-digital audio amplification. The efficiency of this digital amplifier is typically 90%, reducing the size of both the power supplies and heatsinks needed. The applications of the TAS5112DFD include DVD Receiver, Home Theatre, Mini/Micro Component Systems and Internet Music Appliance.
