4. Summary

Many analog systems require isolation to provide safety, level shifting or to mitigate ground noise. ISOamps are a

common but expensive solution that lack flexibility and force the designer to compromise and/or add supplemental

circuitry to a design.

Silicon Labs' ISOlinear reference design (Si86IsoLin-EVB) offers a lower-cost, more flexible linear isolation

solution. This design is enabled by the Silicon Labs Si86xx industry-leading digital isolator and requires only four

operational amplifiers and some passive components in addition to the isolator. The ISOlinear reference design

benefits the user with a robust, competitive solution and the opportunity to create an optimum solution for the

application at hand at a fraction of the price of an ISOamp.
