The MAX4004/MAX4006 precision, high-side, current
monitors are specifically designed for monitoring photo-
diode current in fiber applications. 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 current monitors have six decades
of dynamic range and monitor reference current of
250nA to 2.5mA with better than 5% accuracy. The
photodiode current can be monitored from 10nA to
10mA with reduced accuracy.
The MAX4004/MAX4006 accept a +2.7V to +22V supply
voltage, suitable for PIN photodiode applications. (For
higher voltage applications, refer to the MAX4007/
MAX4008 data sheet.) Internal current limiting (20mA,
typ) protects the device against short-circuit-to-ground or
excessive current conditions. A clamp diode protects the
monitor output from overvoltage. Additionally, these
devices feature thermal shutdown if the die temperature
reaches +150°C.
The MAX4004/MAX4006 are available in tiny, space-
saving 6-pin SOT23 packages, and operate over the
extended temperature range of -40°C to +85°C.
