Hello,
I'm interested in using one of the TI digital isolation devices ISO7220 or perhaps the ISO7520 in an analog application. In reference to the the Texas Instruments "Interface Guide", page 10,
http://focus.ti.com/lit/sg/sszt009d/sszt009d.pdf
there is listed a key feature that specifies the signaling rate at 0 Mbps to 200 Mbps and passes DC single levels. My need is to pass only analog on channel "A" any given analog level between 2.5 to 4.2 volts, and channel "B" a zero reference voltage. My questions are:
1) Is there any reason that I could not use this chip in an analog application?
2) Is the input / output linear and if so, what is the accuracy spec for the input to the output of a channel?
