2X15 Watt stereo amplifier using TDA4935

Posted on Feb 4, 2014

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. Hi Sicko With 20 volt DC the output will be 11watts into 4 ohms as per mfg datasheet, at an efficiency of 70%. Hence the power input required for the chip is around 16watts 16/20 is 800mA both channel put together 1. 6Amps. with head room 20volt 2amp transformer is the best choice.
