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.
