Pcb Power Tda 2003
Tda2003 stereo amplifier pcb outline.
Pcb power tda 2003. It s typically used for car audio amplifiers but it also works great as a bedroom amp or anywhere else you need good audio without tons of power. Speaker k1 can be a 4 ohm one. Input ground and output ground must be properly decoupled. In particular the tda 2003 can drive a coupling transformer for audio modulation.
Inductive load a protection diode is provided between pin 4 and 5 see the internal schematic diagram to allow use of the tda 2003 with inductive loads.

Dc voltage the maximum operating dc voltage on the tda 2003 is 18v. Stereo and bridged amplifier pcbs are available for this project.
Which it uses the supply voltage from 12 volt car battery. Tda2003 stereo amplifier schematic. The tda2003 amplifier ic delivers a 7 watt output power using a 12v 500ma power supply with a 4ω speaker. I designed the pcb in kicad as a single board of 35 by 85 millimeters that holds both channels.
The ic can easily deliver 10w to a 4 ohms load speaker. If you are further interested in tda2003 related topics i have another post car audio amplifier using tda2003. The tda2003 is a low cost audio chip amplifier that can put out some really nice sounds. Pcb layout for this circuit can be found on the datasheet of tda2003.
Tda2003 must be fitted with a heat sink. The pins 5 3 power the amplifier ic and the audio signal to be amplified is given in through pin 1 which is the non inverting input. It is used for music amplifier in for car audio. Use 18v dc for powering this circuit.
A three pin header is used as audio input and screw terminals are present at supply voltage port and audio output ports.
