ISO120 is not recommended for new designs
Although this product continues to be in production to support previous designs, we don't recommend it for new designs. Consider one of these alternates:
open-in-new Compare alternates
Same functionality with different pin-out to the compared device
ISO121 ACTIVE ±10-V input, precision voltage sensing isolated amplifier Designs can achieve better performance
Similar functionality to the compared device
ISO224 ACTIVE ±12-V input, precision voltage sensing reinforced isolated amplifier Smaller package with higher isolation rating, but similar input voltage range
