MAX4007EUT+T
High-Accuracy, 76V, High-Side Current Monitors in SOT23
General Description
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.

Current Monitors in SOT23
Functional Diagrams
Detailed Description
The MAX4007/MAX4008 are versatile current monitors
intended for monitoring DC photodiode current in fiber
applications (see Functional Diagram). The MAX4007
output is a current that is exactly one-tenth the refer-
ence current. The MAX4008 outputs a voltage that is
proportional to the reference current with a transimped-
ance gain of 1V/mA achieved by a factory-trimmed,
internal 10kΩresistor.
Both current devices have six decades of dynamic
range and monitor reference current ranging from
250nA to 2.5mA, the nominal operating range, with bet-
ter than 5% accuracy across the entire reference cur-
rent, bias voltage, and temperature ranges. The
corresponding monitor outputs produce 25nA to
0.25mA (MAX4007) and 0.25mV to 2.5V (MAX4008).
When the reference currents are extended to the
broader range of 10nA to 10mA, an accuracy of less
than 10% is maintained. Internal current limiting (20mA,
