High-Accuracy, 76V, High-Side

Current Monitors in SOT23

General Description

Features

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.

♦ Wide Reference Current Dynamic Range

Guaranteed 250nA to 2.5mA with 5% Monitor

Accuracy

Extended 10nA to 10mA with 10% Monitor

Accuracy

♦ Current (MAX4007) or Voltage (MAX4008) Monitor

Outputs

♦ Reference Current-Limit Protection (20mA, typ)

♦ Voltage Clamp Protects Subsequent Output

Circuitry

♦ +2.7V to +76V Wide Voltage Range Operation

♦ 6-Pin SOT23 Packages

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.
