The 3650 and 3652 are optically coupled integrated circuit isolation amplifiers. Prior to their introduction commercially available isolation amplifiers had been modular or rack mounted devices using transformer coupled modulation demodulation techniques. Compared to these earlier isolation amplifiers, the 3650 and 3652 have the advantage of smaller size, lower cost, wider bandwidth and integrated circuit reliability. Also, because they use a DC analog modu-lation technique as opposed to a carrier-type tech-nique, they avoid the problems of electro-magnetic interference (both transmitted and received) that most of the modular isolation amplifiers exhibit.
