With only one active integrated circuit TDA 2003 as component this circuit can provide up to 10W of audio power to the load which can be between 2 and 8 ohm.
As usual integrated circuit TDA2003, should be placed with which appropriate heat sink to prevent damage to internal components on the temperature of the IC.
10 W audio amplifier circuit requires a current to voltage V max 18VDC 2A to work correctly.
The low power audio amplifier is obtained at the optimal point of the work load of 4 Ω. These entries must be at least 1Vpp to achieve this performance.
