Product Summary

The INA138NA is designed as one kind of high-side measurement current shunt monitor that can be used in current shunt measurement automotive, telephone, computers; portable & battery backup systems; battery chargers;power management and so on. This device converts a differential input voltage to a current output and this current is converted back to a voltage with an external load resistor that sets any gain from 1 to over 100.

Parametrics

Absolute maximum ratings of the INA138NA/3K can be summarized as:(1)Lead Temperature (soldering, 10 s): +300°C;(2)Junction Temperature: +150°C;(3)Storage Temperature: -55°C to +125°C;(4)Operating Temperature: -55°C to +125°C;(5)Analog Output, Out: -0.3 V to 40 V.
