LM4756 Dual 7W Audio Power Amplifier w/Mute, Standby and Volume Control
General Description
The LM4756 is a stereo audio amplifier capable of delivering 7W/channel at 10% distortion into a 4 or 8 load.

The power amp has an internally set gain of 30dB. A 0V­5V 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 fade-in/out mute and a power conserving standby function which are controlled through TTL or CMOS logic. Both functions provide over 75dB of attenuation. The LM4756 maintains an excellent Signal-to-Noise ratio of greater than 70dB with a low noise floor less than 2mV. The IC also maintains above 50dB of channel separation. The LM4756 is available in a 15-lead non-isolated plastic package and is designed for use in TV applications requiring single supply ope
