Surround Power Amplifier LM3886

Power Amplifier LM3886 
Audio Power Amplifier is an important part in the reproduction of sound in a sound system. Audio Power Amplifier LM 3886 with power IC Audio Power Amplifier is a highly capable and able to produce 68 Watts with power rata2 4Ohm load and capable of producing power 38 Watt with 8Ohm load. 
With good sound reproduction capabilities of 20Hz-20kHz is also included on this LM3886 Audio Power Amplifier. LM3886 Audio Power Amplifier is equipped with spike protection that will protect the output circuit from overvoltage, undervoltage, overloads, konrsleting power supply, thermal runawaydan peak temperature. Audio Power Amplifier LM3886 also features a noise reduction system which can keep the audio from the noise well.
