LM4863 Amplifier IC DIP-16 Best price , good quality,and fast delivery General DescriptionThe LM4863 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.2W to a 4Ù load (Note 1) or 2.5W to a 3Ù load (Note 2) with less than 1.0% THD+N. In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones.Boomer audio power amplifiers were designed specifically to provide high quality output power from a surface mount package while requiring few external components. To simplify audio system design, the LM4863 combines dual bridge speaker amplifiers and stereo headphone amplifiers on onechip. The LM4863 features an externally controlled, low-power consumption shutdown mode, a stereo headphone amplifier mode, and thermal shutdown protection. It also utilizes circuitry to reduce “clicks and pops” during device turn-on.Note 1: An LM4863MTE or LM4863LQ that has been properly mounted toa circuit board will deliver 2.2W into 4Ù. The other package options for theLM4863 will deliver 1.1W into 8Ù. See the Application Information sectionsfor further information concerning the LM4863MTE and LM4863LQ.Note 2: An LM4863MTE or LM4863LQ that has been properly mounted to acircuit board and forced-air cooled will deliver 2.5W into 3Ù.Key SpecificationsPO at 1% THD+NLM4863LQ, 3Ù, 4Ù loads 2.5W(typ), 2.2W(typ)LM4863MTE, 3Ù, 4Ù loads 2.5W(typ), 2.2W(typ)LM4863MTE, 8Ù load 1.1W(typ)LM4863, 8Ù 1.1W(typ)Single-ended mode THD+N at 75mW into32Ù 0.5%(max)Shutdown current 0.7μA(typ)Supply voltage range 2.0V to 5.5VFeaturesStereo headphone amplifier modeClick and pop” suppression circuitryUnity-gain stableThermal shutdown protection circuitrySOIC, TSSOP, exposed-DAP TSSOP, and LLPpackages* Not recommended for new designs.
