Мониторы и регуляторы тока и мощности MAX4007EUT+T

The MAX4007EUT+T is a high-accuracy, 76V, high side current monitor in 6 pin SOT-23 package. This precision, high-side current monitor is specifically designed for monitoring photodiode current in fibre applications. It offers 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 current. The current monitors 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 monitored from 10nA to 10mA with reduced accuracy. It is suitable for APD or PIN photodiode applications. 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 temperature reaches +150°C.

• Supply voltage range is 2.7V to 76V
• Operating temperature range from -40°C to 85°C
• Typical accuracy of 5%
• Bias quiescent current is 90µA
