Description
The MC4863PD 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 addition, the headphone input pin allows the amplifiers to operate in single-ended mode to drive 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, it combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.
Features
1. Single-ended mode – THD+N 0.5%(max) at 75mW into 32Ω
2. Shutdown current 0.7μA(typ)
3. Stereo headphone amplifier mode
4. “Click and pop” suppression circuitry
5. Unity-gain stable
6. Thermal shutdown protection circuitry
