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
load. The power
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.
