LTK5130

The LTK5130 is a Class F audio power amplifier chip from LTKCHIP. It is a single-ended input single-channel amplifier with a maximum output power of 11W at 2Ω and can operate from a power supply voltage of 3V to 7.5V. The chip features a high voltage resistance of up to 7.5V, a one-pulse function to control the power amplifier's on/off, AB/D class mode switching, and AB/D class mode switching. It also has a new filterless structure to eliminate the need for traditional Class D power amplifier output low-pass filters. Check the detailed ltk5130 datasheet above to learn more.

Detailed Description of Key Features

• One-Pulse Function: The one-pulse function is a convenient way to control the power amplifier's on/off and AB/D class mode switching. With this function, you can control the power amplifier with just a single pulse signal.
• AB Class Mode: AB class mode is a traditional class of power amplifiers that offers good sound quality and efficiency. The LTK5130's AB class mode is ideal for applications where sound quality is the most important factor.
• Class D Amplifier Mode: Class D amplifier mode is a more modern class of power amplifier that offers very high efficiency. The LTK5130's class D amplifier mode is ideal for applications where efficiency is the most important factor, such as portable devices.
• Filterless Structure: The LTK5130's filterless structure eliminates the need for traditional Class D power amplifier output low-pass filters. This makes the LTK5130 easier to design and reduces the cost and size of the overall circuit.
