Si86xxIsoLin-UG Si86XX ISOLINEAR USERS GUIDE 1. Introduction The ISOlinear reference design modulates the incoming analog signal, transmits the resulting digital signal through the Si86xx digital isolator, and filters the resulting output-side data to reconstruct the analog input signal. Key applications include: isolation amplifier for sensors, ground loop elimination, level shifting, and motor control. The ISOlinear reference design offers the user an alternative to expensive analog isolation amplifiers, with the added benefits of competitive performance and greater economy and user-flexibility. This reference design contains three different cost/performance-optimized analog isolation circuits. The heart of the ISOlinear reference design is the Si86xx digital isolator. The Si86xx is a family of high- performance, CMOS-based galvanic isolators designed for industrial, commercial, and medical isolation applications. With isolation ratings of up to 5 kVrms, these products are available in various channel counts (1/2/3/4/5/6), speeds up to 150 Mbps, and multiple packaging options, including wide-body SOIC-16, narrow body SOIC-16, QSOP-16, and SOIC-8. 2. Kit Contents The Si86xxIsoLin evaluation kit (Si86xxIsoLin-Kit) contains the following: Si86xxIsoLin evaluation board (Si86xxIsoLin-EB) featuring multiple Si8630 150 Mbps digital isolators in a wide-body SOIC-16 package. 2.1.
