TDA4935 Bridge Amplifier Circuit

TDA4935 Bridge Amplifier Circuit
TDA4935 is 2x15W top quality audio amplifier IC from Siemens. The IC can be employed in stereo mode or bridge mode. In stereo mode it will deliver 15W per channel and in bridge mode it will deliver 30W into a 8 ohm load at 30V supply. TDA4935 needs very few external parts and contains a wide power supply voltage range. The IC operates in class B mode and has built-in circuitry for over temperature protection 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.
