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
鹵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.
