The TAS257x is mono, digital input Class-D audio amplifier optimized for efficiently driving high peak power into small loudspeakers. Integrated speaker voltage and current sense provides for real time monitoring of loudspeaker behavior. The TAS2563/TAS2781 is a mono, digital input Class-D audio amplifier optimized for efficiently driving high peak power into small loudspeakers. An integrated on-chip DSP supports Texas Instruments Smart Amp speaker protection algorithm. The integrated speaker voltage and current sense provides for real time monitoring of loudspeaker behavior. The TAS5825/TAS5827 is a stereo, digital input Class-D audio amplifier optimized for efficiently driving high peak power into small loudspeakers. An integrated on-chip DSP supports Texas Instruments Smart Amp speaker protection algorithm.
