LTK amplifier

LTK5313 is a built-in adaptive boost F-class audio powerAmplification chip with AGC anti breaking sound function and AB/D modeSwitching, adaptive, ultra-low noise, ultra-low EMI. Adaptive BoostWhen pressed on the output amplitude, the boost circuit does not work when opened, and the power amplifier is directly connectedPowered from the power supply, automatically starts boosting power internally when the output is turned onThe power supply voltage of the amplifier is the boost voltage, achieving a larger outputPower. LTK5313 has four AGC modes to choose from, which can meet the requirementsVarious discordant needs, and protecting the speaker from overload and breakageBad. The chip has AB/D class switching function, which can reduce the amount of AB class switchingThe amplifier interferes with FM. The fully differential structure effectively improves the power amplifier‘s performanceRF noise suppression. Charge Pump boost method, no external requirementInductors, Schottky diodes, and minimizing peripheral components as much as possible,The purpose of cost savings.
