TDA7402TR is a low-power monolithic audio amplifying integrated circuit belonging to “Audio Special Purpose" family. It offers many benefits such as low distortion and higher signal-to-noise ratio in small form factor. This makes it suitable for applications like consumer electronics, active speakers, small amplifiers etc.

TDA7402TR works by using a pair of high voltage, complementary, bifunctional (NPN & PNP) lateral MOSFETs as the input transistors for each channel. This enhances the signal-to-noise ratio and lowers the distortion, so there is less signal noise and reduced distortion of the output audio. The power transistors are then driven by the output of the input transistors to increase the output voltage.

The output stage contains two NPN and two PNP power transistors, achieving excellent performance in terms of low distortion, high output power and high signal-to-noise ratio. It also features two power-on/off control circuits, which provide easy turn ON/OFF control and low current consumption.

TDA7402TR is commonly used in audio amplifiers, active speakers, small amplifiers and other audio application fields. It can easily power several speakers, taking advantage of its low distortion, high power output and high signal to noise ratio, along with the protection circuit built into the device for safe operation.

Additionally, the TDA7402TR can work on a dual supply with symmetrical distortion, meaning that it can be used for both high and low impedance speakers. It also allows for the adjustment of gain, frequency response, and input impedance through external components.

TDA7402TR is a great choice for applications that require good quality audio performance in a small form factor with low power consumption. With its built-in protection circuit and high power output, it is perfect for applications such as audio amplifiers, active speakers, and small amplifiers.
