INTRODUCTION OF MAIN CHIP
LTK5128 is a 5W, mono-channel AB/D mode switching function, ultra-low EMI,
filter-free audio power amplifier chip. LTK5128 can easily switch to AB mode
through a MODE pin, eliminating EMI interference completely. The working
voltage is 2.5V-5.5V, which can provide more than 90% efficiency in class D
amplifier mode. The new filter-free structure can save the low-pass filter of the
traditional class D amplifier, thus saving the system cost and PCB space. It is
an ideal choice for portable applications. LTK5128 adopts the unique DRC
(Dynamic rang control) technology, which reduces the distortion caused by
waveform top cutting. Compared with similar products, the dynamic response
of LTK5128 is better. LTK5128 is packaged in ESOP-8.
