Description

The TMPA208DS is a stereo class-D audio power amplifier with volume control. It delivers up to 2.5W/ch(5W in all) into a 3 ohm load or 2W/ch(4W in all) into a 4 ohm load or 1.25W/ch(2.5W in all) into an 8 ohm load.

With differential input structure, TMPA208DS features high Common Mode Rejection Ratio and Power Supply Rejection Ratio.

Analog input signal is converted into digital output which drives directly to the speaker. High power efficiency is achieved due to digital output at the load. The audio information is embedded in PWM(Pulse Width Modulation).

DC volume control is convenient for LCD projectors, LCD monitors, powered speakers, and other consumer products especially when using remote control.
