The MAX9710 a stereo audio power amplifier IC capable of delivering 3Watts of out put to 4 Ohm loads. MAX9710 can be operated from a single 4.5V to 5.5V power supply , makes it ideal for hand held applications.The IC also features thermal overload protection.
- Use a 5 V DC power supply for powering the circuit.
- If you want to use a battery ,then use a 6V battery with a IN 4007 diode series to the positive terminal of it.The diode will drop 0.7 V and the IC will get the rated ~5V.This is just a safety recommendation .
- Assemble the circuit on a good quality PCB or common board.
