LTK54102
LTK54102 is a high-power, adaptive boost, stereo, PBTL mono, high-efficiency, unfiltered Class D audio power amplifier suitable for single and dual cell lithium battery boosting.
Under the power supply of a single lithium battery, it can reach 2 × 10W at 4 ohms; Under dual lithium battery power supply, it can reach 2 × 20W (10% THD+N) at 4 ohms.
LTK54102 comes with optional spread spectrum function, which can effectively reduce the impact of switching frequency on EMI.
Three different gain mode controls enable LTK54102 to meet accurate requirements for sound quality.
