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,

    The closest part replacement for SSM2141 in terms of your High Voltage common mode requirements with good CMRR performance and also pin-compatible, is the AD8479. Just take note that it has a lower bandwidth, 130 kHz, as compared to SSM2141 which is 3 MHz.

    Let me know if this fits your application requirement.
