LTK5128D Description:
    The LTK5128D is a 4Ω6W, mono Class AB/D audio power amplifier. The LTK5128D can be easily switched to Class AB MODE via a mode pin, completely eliminating EMI interference.
    The LTK5128D operates in a voltage range of 2.5-7V. In Class D amplifier mode can provide more than 90% efficiency, the new filterless structure can eliminate the traditional class D amplifier input low-pass filter, LTK5128D unique Dynamic range control (DRC) technology, reduce the high power output, due to waveform cutting caused by distortion, compared to similar products, The dynamic response is even better. The LTK5128D comes in an ESOP-8 package.
