The LM4753 is a stereo audio amplifier capable of delivering 10W/channel at 10% distortion into a 8[ohm] 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 fade-in/out mute and a power conserving standby function which are controlled through TTL or CMOS logic. Both functions provide over 75 dB of attenuation.The LM4753 maintains an excellent Signal-to-Noise ratio of greater than 70 dB with a low noise floor less than 2 mV. The IC also maintains above 50 dB of channel separation.The LM4753 is available in a 15-lead non-isolated plastic package and is designed for use in TV applications requiring single supply operation.
- Quiet fade-in/out mute function
