2. Silicon Labs’ ISOlinear Reference Design Overview
Silicon Labs offers the ISOlinear reference design (Si86IsoLin), a simple linear isolation circuit that is enabled by
the Si86xx isolator family, offering industry-leading integration, operating performance, and reliability. The Si86xx
isolators are available in UL/VDE/CSA certified isolation ratings of 2.5 or 5 kV. The ISOlinear reference design
architecture is shown in Figure 2. A self-oscillating pulse width modulator (PWM) converts the linear input voltage
into a series of fixed-frequency, variable duty, cycle pulses in which the width of each pulse is proportional to the
sampled input signal amplitude as shown in the waveform diagrams at the bottom of Figure 2. This modulated
(digital) signal is passed through the CMOS digital isolator and then restored to analog format by a fourth-order
analog filter.
Unlike ISOamps, the ISOlinear reference design gives the designer flexibility to craft low-cost, linear isolators that
meet the needs of the end application. For example, the user may elect to relax output ripple requirements to use a
lower order (lower cost) output filter; or modulator performance can be enhanced if higher slew rate op-amps and/
or low-delay comparators are used, and so on.
