DESCRIPTION
The ISO102 and ISO106 isolation buffer amplifiers
are two members of our series of capacitive coupled
isolation products from Burr-Brown. They have the
same electrical performance and they differ in accu-
racy. 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 excep-
tion of missing pins between input and output stages.
This permits utilization of automatic insertion tech-
niques 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 bar-

rier. All elements necessary for operation are con-
tained within the DIP. This provides compact signal
isolation in a hermetic package.
