Schematic Volt

TDA4935 2x15W audio amplifier is high quality Siemens IC. The IC can be used in stereo or bridge mode. In stereo mode can deliver 15W Stereo audio Amplifier using TDA 4935 per channel in bridge mode can deliver 30W to an 8 ohm load at the source of 30V. TDA4935 requires very few external components and has an ample supply voltage range. The IC operates in class B and has built-in protection circuits over temperature and overload protection. 

Notes :

• The circuit must be assembled on a good quality PCB.
• TDA 4935 must be fitted with a proper heat sink.
• The supply voltage can be anything between 8 to 30V DC.
• Capacitors C1, C2, C8 are polyester capacitors.
• Capacitors C3, C4 and C6 are ceramic capacitors while C5 and C9 are electrolytic.
