Audio Amplifiers

The TDA7850 is a monolithic integrated circuit designed and manufactured by STMicroelectronics. It is a high-performance audio amplifier that is specifically designed for use in automotive audio systems.

Description:

The TDA7850 is a single-chip, high-fidelity audio amplifier that is capable of delivering up to 4 x 50 watts of output power into a four-channel load. It is a Class-D amplifier, which means that it uses pulse-width modulation (PWM) to efficiently convert the input signal into a high-power output signal. The chip is housed in a compact 35-pin multi-Watt package.

Features:

Some of the key features of the TDA7850 include:

1. High output power: The TDA7850 can deliver up to 4 x 50 watts of output power into a four-channel load, making it suitable for use in high-fidelity audio systems.
2. Low distortion: The TDA7850 has a low total harmonic distortion (THD) of less than 0.1%, ensuring high-quality audio reproduction.
3. Wide supply voltage range: The TDA7850 can operate from a supply voltage range of 9V to 18V, making it suitable for use in a wide range of automotive applications.
4. Thermal protection: The TDA7850 includes an integrated thermal protection circuit that protects the device from overheating.
5. Soft-start circuit: The TDA7850 includes a soft-start circuit that reduces the in-rush current during power-up, prolonging the life of the device.

Applications:

The TDA7850 is commonly used in a variety of automotive audio applications, including:

1. Car audio systems: The TDA7850 is often used in car audio systems to provide high-quality audio amplification for the vehicle's speakers.
2. Amplified subwoofers: The TDA7850 can also be used to amplify the low-frequency signals from a subwoofer, providing powerful bass output.
3. Multi-channel audio systems: The TDA7850 can be used in multi-channel audio systems, such as those found in home theaters or professional audio setups.
4. Sound reinforcement systems: The TDA7850 can be used in sound reinforcement systems, such as those used in concert venues or public address systems.

Overall, the TDA7850 is a high-performance audio amplifier that is well-suited for use in a wide range of automotive and audio applications. Its high output power, low distortion, and thermal protection features make it a popular choice for audio enthusiasts and professionals alike.
