LTK5210 Description:
    The LTK5210 is a 3-ω-7.9W dual-channel Class F audio power amplifier with headphone switching.
     The LTK5210 can switch between headset mode and power amplifier mode. When the chip switches to headset mode, the internal circuit of the chip can drive the stereo headset, and the power amplifier mode can be switched to the stereo speaker.
    The LTK5210 also uses a high pressure process, which can withstand up to 7V. At the same time, it has a first-line pulse function, which can control a single pin to make the chip enter Class D, Class AB mode, and off mode, to achieve the purpose of saving IO port, and the LTK5210 can completely eliminate EMI interference in Class AB mode. In Class D amplifier mode, it can provide more than 90% efficiency. The new filterless structure can eliminate the low-pass filter of traditional class D amplifier. LTK5210's unique RCDynamicrange control (RCDynamicrange control) technology reduces the distortion caused by waveform cutting during high-power output. The dynamic response is even better.
    The LTK5210 is packaged in ESOP_10
