LM4663MT/NOPB is aimed at the audio linear field and is used in amplifiers. It is a dual-channel, low-voltage power amplifier. This power amplifier is designed for space-saving high-efficiency, low-noise and low distortion audio applications, including battery-operated products, supporting power classes such as Class AB and Class D. The LM4663MT/NOPB has two bridge terminals on one side and single-ended terminals on the other side. This power amplifier is equipped with two separate charge pumps and supports outputs of 2.7V-13.2V.

The LM4663MT/NOPB works on the principle of amplifying the audio signal while providing a specific amount of electrical energy to power the driver circuit. The input signal is amplified by two op-amp circuits which double the current and voltage of the input signal. This amplified signal is then sent to the output drivers through the bridge terminals. The drivers then convert the signal into an electrical current which is sent to the output terminals to provide voltage and current gain.

The major advantage of this amplifier is its low power consumption. It consumes much less power than Class AB amplifiers, making it suitable for portable audio devices such as mp3 players, mobile phones and laptops. The power output of the amplifier is much higher than Class AB amplifiers, making it ideal for high-powered audio systems. The amplifier also has excellent noise and distortion performance, making it a good choice for professional audio engineering.

The LM4663MT/NOPB features adjustable gain up to 18dB, which helps to reduce distortion at higher power levels. It also includes an internal protection circuit, which protects the amplifier from over voltage, over current and over temperature. This amplifier is ideal for use in professional audio systems and can be used in mono, stereo or surround sound applications.

The LM4663MT/NOPB is a great choice for battery-operated applications, due to its low power consumption and high power output. It is also highly efficient, with a typical efficiency curve of 93%, indicating that the amplifier is capable of producing higher voltage levels than other traditional amplifiers. This high efficiency helps to reduce the overall power consumption of the device, which is an important factor when building audio devices.

The LM4663MT/NOPB is an ideal choice for professional audio engineering, due to its high power output and low power consumption. Its adjustable gain settings and protection circuit make it an excellent choice for battery-operated applications, while its high efficiency and excellent noise and distortion performance make it a great choice for high-end audio systems.
