LM4753

Dual 10W Audio Power Amplifier w/Mute, Standby and

Volume Control

General Description

The LM4753 is a stereo audio amplifier capable of delivering

10W/channel at 10% distortion into a 8

amp has an internally set gain of 30 dB. A 0V–5V DC con-

trolled volume block provides 80 dB of attenuation from input

to line-out. Line outputs are available after the volume con-

trol 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.
