They have the same electrical performance and they differ in accuracy.
The ISO102 is rated for 1500Vrms in a 24-pin DIP.
The ISO106 is rated for 3500Vrms in a 40-pin DIP.
Both side-brazed DIPs are 600mil wide and have industry standard package dimensions with the exception of missing pins between input and output stages.
This permits utilization of automatic insertion techniques in production.
The three-chip hybrid with its generous high voltage spacing is easy to use (no external components are required).
Each buffer accurately isolates ±10V analog signals by digitally encoding the input voltage and uniquely coupling across a differential ceramic capacitive barrier.
All elements necessary for operation are contained within the DIP.
This provides compact signal isolation in a hermetic package.
