... They offer a connec- tion point for the reference current and a monitor output that produces a signal proportional to the reference current. The monitor output of the MAX4004 is a current proportional to the reference current. The monitor out- put of the MAX4006 is a voltage proportional to the ref- erence current ...

... The MAX4004/MAX4006 are versatile current monitors intended for monitoring DC photodiode current in fiber applications (see the Functional Diagram). The MAX4004 output is a current that is exactly one-tenth of the reference current. The MAX4006 outputs a voltage that is proportional to the reference current with a tran- simpedance gain of 1V/mA achieved by a factory- trimmed, internal 10kΩ ...

... DC measurements are required. Determining the required filtering components is straightforward, as the MAX4004 exhibits a very high output impedance (>5MΩ), while the MAX4006 exhibits an output resis- tance of 10kΩ. In some applications where pilot tones are used to iden- tify specific fiber channels, higher bandwidths are desired at OUT to detect these tones ...
