DESCRIPTION
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.

ELECTROSTATIC DISCHARGE SENSITIVITY This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degrada- tion to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
