Kit 27. 1W TDA7052 POWER AMPLIFIER This is a 1 watt mono amplifier Kit module using the TDA7052 from Philips. (Note, no suffix.) It is designed to be used as a building block in other projects where a battery powered, audio amplifier is required. The kit is constructed on a single-sided printed circuit board (PCB). Protel Autotrax and Schematic were used to design the board. ASSEMBLY INSTRUCTIONS Assembly is straight forward. Make sure you get the integrated circuit and the capacitors are the correct way around. The electrolytic capacitors are polarized; they have a + or - marked on them and they must be inserted correctly into the PCB. CIRCUIT DESCRIPTION The data sheet contains all the necessary information about the TDA7052. You may download it from the software download page on our website at http://kitsrus.com/soft.html Here are the main points: the module has a low component count no external heatsink is needed it is short circuit protected ideal for 3V - 15V battery operation into an 8 ohm speaker COMPONENTS Capactors: 2.2uF electrolytic C1 100nF ceramic/mono C2 100uF electrolytic C3 Kit 27 PCB 10K Piher log potentiometer 1K resistor 5%, 1/4W R1 Spindle for potentiometer TDA7052 chip 8 pin IC socket 1 1 1 1 1 1 1 1 1
