I have googled and then only I posted over here. I have already checked that page and some from Analog Devices. Thats why I mentioned tested. Moreover those IC are expensive over here and not easily available. If someone can recommend some IC those are cheap and readily available.
Thanks for response Peter. My requirement is I am trying to make a smart hoem audio system where I can select different input sources and output sources for audio. It's going to be POE (Using buck conveter if required) operated from the micro. The cahnnel can be any (2,4,8)depending upon the cost . The control interface can be direct digital or any protocol. Hope I am clear
If you want good audio performance in HiFi terms then you must expect to pay for nice solid state switches.
You need to decide if you need +/- 15V signal levels or can manage with 0-5V.
Unless you do some tricks (basically shorting out the signals you don't want rather than passing the one you do want though the switch) then you will find that the multiplexer can easily be the dominant source of noise and distortion in your system.
So before I could advise a particular chip you need to specify:
normal (or reference) signal level
required distortion at that level
signal to noise ratio at reference level
maximum signal level
frequency response
maximum permitted feed-through of unwanted channels at defined frequency and level
You have to tell me about signal levels before I can suggest anything, Analog Devices make switches with maximum signal handling in the range 0-3v at the lowest up to +/-20V for high voltage chips. There is a big range of cost and other performance parameters as well.
