N8822WT products are belong to audio power amplifier integrated circuit. This product is suitable for car stereo, home theater, multimedia audio system and other audio output system due to its excellent performance and competitive price.

The N8822WT audio power amplifier integrated circuit is designed based on two principles: Class-D and Class-AB. This dual-mode power amplifier is available in two packages, SOT23-5 and quad flat no-lead (QFN) 1.27*1.27 mm (base 16). The chip integrates a low external component counts implementation of a two-output, Class-AB/D switching bridge driver combined with a Class-D amplifier.

The N8822WT integrated circuit is mainly used in automotive sound system, home audio, multimedia speaker and other audio equipment. The main advantages of using the integrated circuit are its high integration, low power consumption and small size. The N8822WT can be used as an audio bridge driver and an amplifier in one chip, which can save space. Compared with other integrated circuits, it has lower output ripple and higher switching frequency. The power supply voltage range is 4V-20V, which make it suitable for a wide range of applications.

The working principle of the N8822WT is based on the Class-D and Class-AB switching bridge architecture. The bridge structure integrates a low external component counts implementation of a two-output, Class-AB/D switching bridge driver combined with a Class-D amplifier.It amplifies the audio signal provided by the power supply to drive the speakers in the output. At the same time, it also provides the corresponding port for the amplifier control.

The main control signal of the N8822WT is the power amplifier control pin toggle signal. When the toggle signal changes from low to high, the output of the amplifier is changed accordingly. When the toggle signal is 0, the power is not output; when the toggle signal is 1, the output power is in the specified range. The N8822WT also has over-current and over-temperature protection functions, and the output channel can be short-circuit protection.

In summary, N8822WT is an integrated circuit designed for audio power amplifier applications. It has the advantages of high integration, low power consumption and small size. With its excellent performance and competitive price, it is highly suitable for automotive sound systems, home audio, multimedia speaker and other audio devices.
