This is TDA2009 bridge amplifier circuit BCL 18W,Supply volt = 23V 2A
The TDA2009 be 10 +10W STEREO AMPLIFIER integrated circuits interesting again the one number. We try to bring do the circuit amplifies 18W sizes better or Power Amplifier BCL 18W by IC TDA2009. Be circuit character model 18W Bridge amplifier the sound better model OTL amp. By use power supply just one group be 23V only. Make good convenient. When use 4 ohm loudspeakers. Will give the electric power about 18watt or 20Watt. If you want to the system stereo as a result just build enhance again the circuit. Request have fun 18W Bridge amplifier TDA2009.
