3656BG [Texas Instruments]

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 accomplished 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 configurations to match the requirements of many different types of isolation applications.
