Hello all readers, at this time I will discuss a series of mini-amplifier with simple quick, easy, and useful to make by relying on the IC TDA 2003.
Components:
IC TDA2003 (
a refinement of the previous type TDA 2002)
R1= 220 ohms
R2= 2,2 ohms
R3= 1 ohms
C1= 10 uF, Electrolyte Capacitor
C2= 470 uF, 25V, Electrolyte Capacitor
C3= 100 nF
Speaker= 8ohms, 3W speaker
VR 50 K untuk volume control
The following photo kit finished and ready for use:
This mini audio amplifier IC TDA2003 cored, can be used for HiFi power amplifier, musical instrument amplifier, car audio amplifier, and a radio receiver. could use a supply voltage of 12 volt car battery, and 8 Volts when using Li-ion batteries are strung together series. when used in the power supply can be changed up to 15 Volts. This makes it possible to get a higher watt power. The TDA2003 IC has protective damage due to short circuit, when the load exceeds the limit. The maximum voltage is 28 Volts.
