The LM4865MMX/NOPB is an integrated audio amplifier application chip designed for use as a low voltage dual-amplifier audio amplifier. It\'s a two-channel power amplifier designed to supply up to 890 mW of power. It features high efficiency, low noise, low distortion, and small size. This makes it suitable for applications such as portable audio devices, audio systems, and audiovisual equipment.

The LM4865MMX/NOPB includes integrated thermal protection, which helps protect the amplifier from thermal damage due to high operating temperatures. This thermal protection can help ensure the audio amplifier is reliable in typical applications, reducing thermal performance variability and increasing product life.

The LM4865MMX/NOPB contains two separate audio amplifiers, each with its own power supply voltage. The input signals of both amplifiers is designed to accept a variety of inputs, such as analog and digital. The user can select the desired input signal through an external switch, which can be used to simultaneously switch the two input signals to either the left or the right outputs. This feature allows for a more efficient and versatile operation of the amplifier.

The LM4865MMX/NOPB utilizes a low voltage (1.62 V to 5.5 V) supply voltage, making it suitable for applications requiring a low power supply voltage. The output power range is 0.5 W to 890 mW, depending on the power supply voltage and the input signal. This makes the LM4865MMX/NOPB suitable for low-voltage audio applications where low power is desired.

The LM4865MMX/NOPB is designed to work in a wide variety of frequencies. This allows for flexibility in designing audio systems. The amplifier can be configured for digital signals ranging from 10 kHz to 25 kHz and for analog signals ranging from 20 Hz to 20 kHz and beyond. This makes it suitable for audio systems employed in a wide range of application areas, such as music and digital audio, multimedia applications, automotive systems, and other consumer electronics products.

The working principle of the LM4865MMX/NOPB is to convert the input signals into sound waves. These signals are amplified by the amplifier and then sent to the output. The LM4865MMX/NOPB contains an internal voltage booster that enables it to produce high-output power even with a low supply voltage. This feature makes the LM4865MMX/NOPB ideal for low-voltage audio applications.

In addition to high-power output and low supply voltage requirements, the LM4865MMX/NOPB also features low distortion and noise. The integrated temperature protection and high efficiency of the amplifier makes it a reliable option for applications where high audio quality is important. The LM4865MMX/NOPB also features low power consumption, making it suitable for battery-operated devices and applications.
