LM48510

The LM48510 is designed as one kind of boosted class D audio power amplifier that can provide 1.2W continuous power into an 8 speaker when operating on a 3.3V power supply with boost voltage (PV1) of 5.0V.And it is capable of driving a 4 speaker load at a continuous average output of 1.7W with less than 1% THD+N.The Class D amplifier is a low noise,filterless PWM architecture that eliminates the output filter,reducing external component count,board area consumption,system cost and simplifying design.

Features of the LM48510 are:(1)click and pop suppression;(2)low 0.01A shutdown current;(3)76% efficiency;(4)filterless class D;(5)2.7V-5.0V operation (VDD);(6)externally configurable gain on class D;(7)very fast turn on time:17s;(8)independent boost and amplifier shutdown pins.It can be used in mobile phones,PDAs,portable media,cameras and handheld games.

The absolute maximum ratings of the LM48510 can be summarized as:(1)supply voltage:6 V;(2)storage temperature:-65°C to +150°C;(3)input voltage:-0.3V to VDD+0.3V;(4)power dissipation:internally limited;(5)ESD susceptibility:2000 V;(6)ESD susceptibility:200 V;(7)junction temperature:150°C;(8)thermal resistance:37°C/W;(9)temperature range:-40°CTA+85°C.If you want to know more information such as the electrical characteristics about the LM48510,please download the datasheet in www.seekic.com or www.chinaicmart.com .
