LM4756 Dual 7W Audio Power Amplifier

The LM4756 is a stereo audio amplifier capable of delivering 7W/channel at 10% distortion into a 4Ω or 8Ω load. The power amp has an internally set gain of 30dB. A 0V–5V DC controlled volume block provides 80dB of attenuation from input to line-out. Line outputs are available after the volume control for signal routing. The amplifier has a smooth transition .
