A straight forward circuit diagram of a 3W stereo amplifier circuit using MAX 7910 IC is given here. This 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 MAX9710Â a stereo audio power amplifier IC capable of deliveringÂ 3WattsÂ of out put to 4 Ohm loads. MAX9710 can be operated from aÂ single 4.5V to 5.5V power supply, makes it ideal for hand held applications. The IC also features thermal overload protection.
Circuit Diagram with Parts list.Â
- 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 4007Â diode series to the positive terminal of it.The diode will drop 0.7 VÂ and the IC will get the rated ~5V.This is just a saftey recommendation .
- Assemble the circuit on a good quality PCB or common board.
