The TDA7256 is a powerful monolithic integrated circuit in a Multiwatt15 package, primarily intended for audio applications.

It is a Class AB Complementary Symmetry Amplifier (CSLA) intended for use as high fidelity audio power amplifier in stereo applications. It offers excellent sound quality and a high output power while keeping a high efficiency, making it able to fit in a wide variety of audio systems.

The TDA7256 can be configured for single Ended and push pull operation, with an output power in excess of (25W/8Ω) with a single supply voltage between 12V and 18 V. It is recommended to use stabilised power supply to achieve constant performance at any supply voltage.

The TDA7256 also features a low harmonic distortion, crosstalk attenuation and thermal protection that prevents dangerous temperatures and unexpected shutdown in case of overload/short circuit.

In terms of application field, the TDA7256 is suitable for home audio applications, portable systems, car audio systems and the industry, where audio programming and sound reinforcement are the main tasks. Small overall dimensions and a low external components count compared to typical complementary Class AB amplifiers make the TDA7256 an ideal solution for space saving.

When it comes to the working principle of the TDA7256, it is a complementary Class AB amplifier built with an inversion amplifier, a driver stage and an output stage. The output stage is made up of transistors arranged as a bridge that connect the speaker to the power supply. The output transistors operate in Class AB mode, with very low distortion and noise. The driver stage consists of two complementary transistors that amplify the signal coming from the preamplifier. Finally, the input stage has two high-performance transistors that perform the signal inversion.

To sum up, the TDA7256 is a powerful CSLA amplifier integrated circuit which offers an excellent quality and high efficiency for audio power amplifier in stereo applications. This device is particularly suitable for home audio, car audio and portable systems, and its compact size makes it an ideal solution for space saving. In addition, the working principle is based on a complementary Class AB amplifier built with two transistors that act as the input stage, a driver stage and an output stage.
