Description

The LM4876MMX is designed as a bridge-connected audio power amplifier capable of delivering typically 1.1W of continuous average power to an 8ohms load with 0.5% THD from a 5V power supply.

LM4876MMX has six features. (1)No output coupling capacitors, bootstrap capacitors, or snubber circuits are necessary. (2)Small outline packaging. (3)Unity-gain stable. (4)External gain configuration capability. (5)Pin compatible with LM4861 and LM4871 applications. (6)Typical applications include mobile phones, portable computers, desktop computers and low voltage audio systems. Those are all the main features.

Some absolute maximum ratings of LM4876MMX have been concluded into several points as follow. (1)Its supply voltage would be 6.0V. (2)Its storage temperature range would be from -65°C to 150°C. (3)Its input voltage would be from -0.3V to Vdd+0.3V. (4)Its power dissipation would be internally limited. (5)Its ESD susceptibility would be 5000V. (6)Its junction temperature would be 150°C. (7)Its soldering information would be small outline package would be 215°C for vapor phase 60 seconds and would be 220°C for infrared 15 seconds. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of LM4876MMX are concluded as follow. (1)Its supply voltage would be min 2.0V and max 5.5V. (2)Its quiescent power supply current would be typ 6.5mA and max 10mA. (3)Its shutdown current would be typ 0.01uA and max 2uA. (4)Its output offset voltage would be typ 5mV and max 50mV. (5)Its output power would be min 1.0W and typ 1.1W. (6)Its total harmonic distortion+noise would be typ 0.25%. (7)Its power supply rejection ratio would be typ 65dB. And so on. At present we have not got so much information about this IC and we would try hard to get more information about this IC.
