LM4753 Dual 10W Audio Power Amplifier

The LM4753 is a stereo audio amplifier capable of delivering 10W/channel at 10% distortion into a 8Ω load. The power amp has an internally set gain of 30 dB. A 0V–5V DC controlled volume block provides 80 dB of attenuation from input to line-out. Line outputs are available after the volume control for signal routing. The amplifier has a smooth transition fad.
