TDA8560Q - 40W Stereo BTL Car Amplifier Circuit

The proposed scheme is straightforward, requiring only a few external electronic components, making it suitable for car audio construction. The output power ranges from 2 to 4 Ohms, providing 2 x 30 W (with a maximum of 2 x 40 W) across two channels in a BTL (Bridge-Tied Load) configuration. The circuit pins are arranged in two rows. The bridge amplifier operates independently of the car speakers. The integrated circuit can handle up to 8.4 A during operation. Additionally, the circuit includes protection mechanisms that block output at temperatures exceeding 150 degrees Celsius. The MUTE and STANDBY functions are controlled via pin 11.

The circuit described is a bridge amplifier designed specifically for automotive audio applications, allowing for efficient power delivery to speakers while minimizing the number of components needed for assembly. In a typical configuration, the amplifier will utilize a dual-channel output, effectively driving two speakers in a stereo arrangement. The output impedance is specified at 2 to 4 Ohms, which is compatible with a wide range of car audio speakers.

The BTL configuration is advantageous as it allows for higher output power without the need for a transformer, thereby reducing weight and space requirements within the vehicle. The maximum output power of 2 x 40 W indicates that the amplifier can deliver substantial audio performance, suitable for driving speakers in a car environment where sound quality and volume are critical.

The integrated circuit's ability to handle up to 8.4 A signifies robust performance, ensuring that the amplifier can deliver peak power when required without distortion. The thermal protection feature is crucial in preventing overheating, which can lead to component failure. By blocking output at temperatures above 150 degrees Celsius, the circuit ensures longevity and reliability in various operating conditions.

The implementation of MUTE and STANDBY functions via pin 11 offers flexibility in managing audio output, allowing users to silence the amplifier when not in use or to enter a low-power state, which is particularly beneficial for battery conservation in vehicles.
