Interface Schematics

Figures 5 and 6 show simplified input and output cir-

cuits of the MAX3942 modulator driver.

To minimize inductance, keep the connections from

OUT, GND, and VEE as short as possible. This is crucial

for optimal performance.

Laser Safety and IEC 825

Using the MAX3942 EAM 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, recogniz-

ing 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 sup-

port 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.
