LTK5208  Description
    The LTK5208 is a 3-ω-7.9W, dual-channel Class F audio power amplifier.
    The LTK5208 adopts a high pressure process and can withstand up to 7V.
    The LTK5208 has a one-line pulse function, which can control a single pin to make the amplifier chip enter the Class D, Class AB MODE, and off mode, to achieve the purpose of saving IO port. If the first-line pulse function is not used, the EN and mode pins can also be controlled separately to easily switch to each working mode. The LTK5208 completely eliminates 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. LTK5208's unique Dynamic range control (DRC) technology reduces the distortion caused by waveform cutting during high-power output. Compared with similar products, dynamic response is better.
    The LTK5208 is packaged in ESSOP-10.
