2,5 Watt audio amplifier circuit diagram

The above is a simple amplifier circuit also has a minimal power output. By using only a few components and a single IC as the basis for the strengthening of the amplifier, this circuit has a power output of not more than 2.5 W and impedance or RL 8. Requires a minimum voltage of this amplifier is around 6V and 26V maximum voltage, the voltage must be DC or already rectified and filtered.
