10 W Audio Amplifier based TDA 2003

Amplifier Circuit — Wed, 23 May 2012 13:35:00 +0000

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. This 10 W audio amplifier circuit requires a current to voltage V max 18VDC 2A to work correctly.

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.

100W Audio Amplifier with Integrated Circuit

The circuit allows an output stage operating at even 2 ohms impedance and gain power 150W. For stability and safety this system decided to make it work with 4 ohm speakers so we gain 100W RMS power.

It allows an output stage operating at even 2 ohms impedance and gain power 150W. For stability and safety this system decided to make it work with 4 ohm speakers so we gain 100W RMS power.

The coil L at the output is formed by 14 turns of wire nr. The separation of the coils is not critical and might leave one beside the next.

The transformer of the power supply must provide 24v + 24v AC in its secondary with a current of 5A for one stage (mono) or 10A for two stages (stereo). While four diodes can be used to make the source 15A is recommended to use a rectifier bridge metal and placed in the corresponding heat sink.

Given their unusual 1.1k resistor values should be accurate. While the output resistance (in parallel with the coil) must be at least 2W of power.

Electrolytic capacitors should be 50V or 63V.

With only one active component of TDA2003 integrated circuit and a single supply source of 8 to 18 volts, this amplifier circuit can provide up to 10W of power to the load which can be between 2 and 8 ohm.

Clearly an integrated circuit, TDA2003, must be mounted with the proper heat sink to prevent damage to internal components from overheating.

At full power the circuit requires 2A to work properly.

10W power can be obtained optimally with 12V 2A and 4 ohm loads. These input must be at least 1Vpp to achieve this performance.
