200mWatt Super Tiny Amplifier using LM386 Circuit Diagram - This is a versatile mini amplifier circuit, a mini amplifier and loudspeaker combination which can be used with a tremendous savings. This mini amplifier requires only a single LM386 IC, a loudspeaker and eight other components.

If measured, requiring only two inches square, 200 mWatt output, or more. If it does not fit, its gain can be preset.

The circuit is very simple. Work is based on IC1 (LM 386) which produces a kind of variation in the specification provide an important distinction, power output and power supply voltage which is a significant factor.

Amplifier is set by the strengthening of the components between legs 1 and 8 and the IC. With RI and C2 (series) reinforcement is set at 50. Without both these components of the circuit will be set on strengthening 20. To gain the maximum 200, C2 is used, and R1 is replaced with a wire channel.

Components List:

R1 = 1k2; P2 = 100 ohms; P1 = 10 k preset potentiometer; C1 = 100 n; C2. C5 = 10u /25 V Tantalum; C3 = 47 n; C4 = 220 u/16V; LS = loudspeaker 8u /0.2…1 W
