TDA7265 is an audio linear amplifier, which is widely used in many areas. It can be used in portable radios, car audio systems, home theatre systems and Hi-Fi audio amplifiers. The TDA7265 amplifier is offered in an integrated circuit (IC) package, featuring high linearity, low power consumption and good audio performance. The amplifier has a wide range of applications, from high-end audio systems to portable audio players.

The TDA7265 amplifier is based on a class AB architecture, which allows it to achieve accurate reproduction of the audio source. It also includes various safety and control functions, such as Precise Input Sensitivity Control, Output Overload Protection and DC Power Supply Offset Removal. This makes the amplifier suitable for a wide range of applications.

The operating frequency of the TDA7265 amplifier is 15 to 42kHz, and the gain is adjustable from 24dB at maximum. The amplifier has a power output of up to 18W, and its distortion is <0.2% at 1kHz and 18W. The power supply voltage range is 6 to 16V.

The TDA7265 amplifier features an improved protection circuit, which ensures better sound quality and protection against over-temperature, over-voltage and over-current conditions. It also includes a selectable mute function, which can be used to reduce noise during short circuit and over-voltage operations.

The working principle of the TDA7265 amplifier is based on the negative feedback principle. The negative feedback is obtained from a reference voltage source, which is compared to the output of the amplifier. The output of the amplifier is then adjusted to reduce distortion and improve linearity. The TDA7265 amplifier also includes other protection features, such as short-circuit protection and current limiting.

In summary, the TDA7265 amplifier is a powerful and reliable audio linear amplifier. It features high linearity, low power consumption and good audio performance. The amplifier is suitable for a wide range of audio applications, including portable radios, car audio systems and home theatre systems. It is based on a class AB architecture, with adjustable gain and a power output of up to 18W. The amplifier includes various safety and control functions, such as Precise Input Sensitivity Control, Output Overload Protection and DC Power Supply Offset Removal. It also includes an improved protection circuit and a selectable mute function. The working principle is based on the negative feedback principle, which is used to reduce distortion and improve linearity.
