Search for a Differential Line Receiver

I'm now making a circuit that requires a large dc voltage between 40 and 100 volts to be coupled to a small ac voltage, and then they are outputted to the circuit together.

We have SSM2141 now, but its input voltage is up to + / -18v. I have also searched other products, and only found some similar products like SSM2142 and SSM2143, which cannot meet my input voltage needs.Therefore, I would like to ask whether you have the product with the same function and circuit design to SSM2141 , which can accept large input voltage.

  • Hi SUN Yajun,

    AD8479 comes with grades, being A and B. B grade has more excellent specs than A grade, specifically the DC specs. The specifications in Table 1, page 3 of the datasheet shows the comparison between the two grades.

    So, if you have tight DC requirements, you could always go with B grade. However, you can go with A grade if its specs are within your application critical parameters.

    Also, the two grades differ in prices. 

    Regards,
