DESCRIPTION
The 3656 was the first amplifier to provide a total
isolation function, both signal and power isolation, in
integrated circuit form. This remarkable advancement
in analog signal processing capability was accom-
plished by use of a patented modulation technique and
miniature hybrid transformer.
Versatility and performance are outstanding features
of the 3656. It is capable of operating with three
APPLICATIONS

Instrumentation
q INDUSTRIAL
Ground Loop Elimination and
Off-ground Signal Measurement
q NUCLEAR
Input/Output/Power Isolation
completely independent grounds (three-port isolation).
In addition, the isolated power generated is available
to power external circuitry at either the input or
output. The uncommitted op amps at the input and the
output allow a wide variety of closed-loop configura-
tions to match the requirements of many different
types of isolation applications.
