MAX4004/MAX4006
High-Accuracy, High-Side Current Monitors
in SOT23
General Description
The MAX4004/MAX4006 precision, high-side, current
monitors are specifically designed for monitoring photo-
diode current in fiber applications. They offer a connection
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 propor-
tional to the reference current. The monitor output of the
MAX4006 is a voltage proportional to the reference cur-
rent. 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 sup-
ply 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
