Hi-Fi 10W audio amplifier circuit based on TDA1910

The circuit design below is a simple Hi-Fi 10W audio amplifier circuit based on TDA1910. If an 8 ohm speaker is used and powered from a 24V DC power supply, this circuit will provide a power output of 10W.

This circuit can operate within the voltage range of 8V – 30V DC, and the recommended power supply is 24VDC. Mount the TDA1910 on a heat sink to prevent overheating and maintain IC performance.

TDA 1910 is a monolithic integrated circuit in MULTIWATT? Packaged for high-fidelity audio power supply applications as high quality television sets.

TDA 1910 complies with DIN 45500 (d = 0.5%) and guarantees an output power of 10W when used at 24V/4W. At 24V/8W, the minimum output power is 7W.

TDA 1910 Features:

Silent facilities

Chip over temperature protection

very low noise

High supply voltage rejection

Low "turn on" noise.
