hello,
Im doing a waveplayer using 8051.i need the amplifier circuit for that.u given this?will it work?please give some suggestions how to achive this project or how better can be done with this project. it is the LM386 which directly interfaces with an 8ohm speaker, through an electrolytic capacitor to decouple the DC. A better alternative would be the electromagnetic buzzer which is around 12mm in dia which is available in 3V, 6V and 12V etc.It is simple to drive with a port pin and a transistor.They are also available with a built in oscilator/driver regards Maharajan |
