LTK5209
The LTK5209 is a 3-ω-7.9W, dual-channel Class F audio power amplifier.
The LTK5209 uses a high pressure process and can withstand up to 7V.
The LTK5209 has a one-line pulse function, which can control a single pin so that the power amplifier chip can enter the Class D anti-break, class D non-anti-break, 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 LTK5209 completely eliminates EMI interference in Class AB mode.
The LTK5209 comes in an ESSOP-10 package.

LTK5209 Description
The LTK5209 is a 3-ω-7.9W, dual-channel Class F audio power amplifier. The LTK5209 uses a high pressure process and can withstand up to 7V.
The LTK5209 has a one-line pulse function, which can control a single pin so that the power amplifier chip can enter the Class D anti-break, class D non-anti-break, 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 LTK5209 completely eliminates EMI interference in Class AB mode. In Class D amplifier mode can provide more than 90% efficiency, the new filterless structure can eliminate the traditional class D amplifier low-pass filter, LTK5209 unique Dynamic range control (DRC) technology, reduce the high power output, due to waveform cutting caused by the distortion. Compared with similar products, dynamic response is better.
