15 Watt Stereo Power Amplifier using TDA4935

TDA4935 is bipolar stereo amplifier IC that can be wired as a 2X15W stereo amplifier or a 30W mono BTL amplifier. The IC also features built in circuitry for over load protection and over temperature shut down. Here the IC is wired in stereo mode in order to deliver 15W power on each speaker. The circuit does not require a dual power supply and it can be powered from anything between 8 to 24V.Here I am using 24V for getting maximum output power.

15 Watt Stereo Power Amplifier using TDA4935

The circuit can be powered from anything between 8 to24V.
Use 20W, 4 Ohm speakers for K1 and K2.
All electrolytic capacitors must be rated at least 25V.

30-watt stereo amplifier with TDA4935

The amplifier is now offer stereo and Class B is designed with the TDA4935 from Siemens, which delivers 15 watts per channel. Can also be configured in BTL or bridge, thus providing 30 watts in mono.

His power depends on the output impedance, ie if you put a 8 ohm speaker, will be supplied with a minimum of 8 and a maximum of 32 volts for this design we chose 24 volts, as recommended in the datasheet ; if placed unabocina 4 ohms, as in our case, the maximum voltage to be applied is 24 volts. It should be mentioned that the ideal supply voltages are at least 8 and a maximum of 26, to guarantee the life of the integrated circuit.

This amplifier has the characteristic of utlized few external components, making it easy to assemble, capacitors and 2 resistors 9

At the moment we do not offer the PCB, but the data sheet can be seen both in design and in BTL stereo configuration, bridge or bridge.

In the BTL configuration you will get a 60 watt amplifier with the assembly of 2.
