National Semiconductor Boomer® LM4863N is a 2-channel Class AB audio amplifier IC designed for high-fidelity audio reproduction. This through-hole component, housed in a 16-DIP package, delivers robust performance with features such as depop, shutdown, and thermal protection. It provides a maximum output power of 3.2W per channel into a 3-ohm load, or 440mW per channel into an 8-ohm load. The LM4863N is suitable for a wide operating voltage range of 2V to 5.5V and operates efficiently across an ambient temperature range of -40°C to 85°C. Its stereo headphone output capability makes it ideal for portable audio devices, multimedia systems, and consumer electronics applications where space and power efficiency are critical.
