The MAX4007/MAX4008 precision, high-side, high-volt-
age current monitors are specifically designed for mon-
itoring photodiode 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
MAX4007 is a current proportional to the reference cur-
rent. The monitor output of the MAX4008 is a voltage
proportional to the reference current. The current moni-
tors have six decades of dynamic range and monitor
reference currents of 250nA to 2.5mA with better than
5% accuracy. The photodiode current can be moni-
tored from 10nA to 10mA with reduced accuracy.
The MAX4007/MAX4008 accept a supply voltage of
+2.7V to +76V, suitable for APD or PIN photodiode appli-
cations. Internal current limiting (20mA, typ) protects the
devices against short circuit to ground. A clamp diode
protects the monitor output from overvoltage. Additionally,
these devices feature thermal shutdown if the die temper-
ature reaches +150°C.
The MAX4007/MAX4008 are available in tiny, space-
saving 6-pin SOT23 packages, and operate over the
extended temperature range of -40°C to +85°C.
