Build a 15W Bridge Audio Amplifier Circuit based TDA2002 . 15W bridge audio amplifier circuit which use 2 pieces of TDA2002. This is audio amplifier for general, work with a single power supply. Use 2A power supply transformer for maximum performance and heatsink should be used to keep the IC from overheating. Build a 15W Bridge Audio Amplifier Circuit based TDA2002 Component part list: R1-5 = 2.7? R2 = 100? R3-4 = 2.2? R6 = 220? R7 = 1M? TR1 = 100K? trimmer C1-9 = 10uF/16V C2-8 = 220uF/16V C3-4-5-7 = 100nF/63V C6=470uF/25V IC1-2=TDA2002 Lsp = 4 – 8?/40W Loundspeaker

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. Via : circuitstoday.com
