AS3047KT - 8W Mono Audio Power Amplifier (TDA2003)
Ability Level 2: ModeratePre-Assembled and Kit versions availableMade in Britain

8 Watt mono audio power amplifier board. Makes an ideal building block for projects where a low voltage dc powered general Class AB audio amplifier is required.

Circuit uses the proven TDA2003 audio amplifier IC that features zero turn-on transients, wide 8 to 18Vdc supply range, current limiting and thermal protection.

Power output is dependent on the supply voltage & load resistance. Over 10 watts is typical for a 2 Ohm speaker with 16V supply; 9V supply with an 8 Ohm speaker will give about 1W.

High quality volume control potentiometer and 8°C/W heatsink included.
