MAX4007EUT+T Datasheet MAX4007EUT+T, MAX4008EUT-T, MAX4007EUT-T | P1-P3

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.

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.
