Input/Output/Power Isolation
This product is covered by the following United States patents: 4,066,974; 4,103,267; 4,082,908. Other patents pending may also apply upon the
allowance and issuance of patents thereon. The product may also be covered in other countries by one or more international patents corresponding
to the above-identified U.S. patents.
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
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.
