LTK5131 Description:
    The LTK5131 is a 2 Ω-11W, anti-crack, single-ended input mono Class F audio power amplifier.
    LTK5131 adopts high voltage withstand technology and can withstand up to 7.5V. LTK5131 has a first-line pulse function and only needs to use one IO port. It can control the switching of power amplifier on and off, Class D anti-break mode, Class D ordinary mode and Class AB mode, which can save IO port for users. It can also control the EN and MODE pins respectively, which can be easily switched to each working mode. In Class AB mode, it can solve the interference problem of traditional class D power amplifier on FM, and completely eliminate EMI interference. In the D-amplifier mode, the efficiency can be higher than 90%, and the new filterless structure can eliminate the output low-pass filter of the traditional Class D amplifier.
    The LTK5131 comes in an ESOP-8 package.
