| Manufacturer | National Semiconductor |
| Overview | The LM4863 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.2W to a 4Ω load (Note 1) or 2.5W to a 3Ω load (Note 2)with less than 1.0% THD+N. In add. 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 which has been properly mounted to the circuit board will deliver 2.2W. |
