LTK5325
LTK5325 is a 2 * 5.3W built-in asynchronous boost audio power amplifier with adaptive boost, anti distortion, and AB/D mode switching.
Adaptive boost has both ultra-low noise floor and ultra-low EMI. When the output amplitude is small, the boost circuit does not work, and the amplifier is directly powered by the power supply. When the output amplitude is large, the boost circuit automatically starts internally. Adaptive boost can improve battery life and extend battery lifespan.

When the output amplitude is large, the boost circuit automatically starts internally. Adaptive boost can improve battery life and extend battery lifespan.
LTK5325 has 2 anti distortion modes to choose from, which can meet various needs and protect the speaker from overload and damage. The chip has AB/D switching function, which can reduce the interference of the amplifier on FM. The fully differential structure effectively improves the RF noise suppression of the power amplifier.
LTK5325 provides SOP16 packaging.
