Circuit Audio Amplifier TDA2003 10 W
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.
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.
