Hello.
can u tell me witch is best audio transmitter and receiver circuit using Lm386 or by other IC.
i want to transmit it by laser or other light source

Thank you.
 

Hi,

simple and good qualitity: use or modify S/PDIF for your needs.

Hope this helps
Klaus
 

An LM386 IC is cheap so its has low output power and is noisy (hiss). It can drive a laser diode up to its maximum output power.
The low power and noise might cause a problem in a receiver.

If you simply modulate the light with AM then there will be interference from many things so high fidelity systems modulate the light with FM.
 

Hi.
can u suggest the IC and specification of the circuit.
if possible can u send me the circuit for the same asap.
Thank you
 

I have never designed a circuit like that. Simply look up the circuit used by wireless headphones. They might use an IC custom-made for them.
