Laser S afety and IEC 825
Using the MAX3261 laser driver alone does not ensure
that a transmitter design is compliant with IEC 825. The
entire transmitter circuit and component selections
must be considered. Each customer must determine
the level of fault tolerance required by their application,
recognizing that Maxim products are not designed or
authorized for use as components in systems intended
for surgical implant into the body, for applications
intended to support or sustain life, or for any other
application where the failure of a Maxim product could
create a situation where personal injury or death may
occur.
