3 Watt Stereo Audio Amplifier
This very simple circuit is ideal for small power audio applications like portable CD players or radio sets.The circuit is designed strictly as per the datasheet and found to be working great.
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.
Notes:
- 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.
