ADG858 for USB?

Hi,

Could you please confirm if I can use two channels of ADG858 for USB data lines? I checked the important specifications (like On resistance, on resistance flatness, matched on resistance, bandwidth) for this device and compared with some devices which are recommended by AD for USB applications, such as ADG787. It seems that the USB requirements are satisfied by ADG858 too. But there is nothing mentioned about USB in ADG858's data sheet. I didn't find an eye diagram in it either.

The reason that I prefer to use ADG858 is that I need its four matched channels and I will be using two of them for USB data lines. Could anyone tell me if I am going wrong about this?

  • Hi Vala,

    Sorry for the late reply.

    For the ADG858, the device is not tested and intended for this application so the performance of the device is not guaranteed.

    If you are looking for a quad 2:1 mux then I suggest to use ADG774 or you may also have a look at ADG787 and ADG772 which are dual 2:1 mux. These are 12Mbps switching compliant and is best suitable for applications that supports USB data lines.

    Hope this helps.
