INA139NA
Brand: Texas Instruments
The INA139NA is a high-side current-sense amplifier that measures shunt current on the supply side while keeping the load ground-referenced, with gain set by a single external resistor for flexible full-scale ranging. A 2.7 V to 36 V common-mode range and -40°C to +125°C rating in a 5-pin SOT-23 suit compact battery, motor and industrial power-supply current-monitoring designs.

Analog Features & Applications
- High-side current sensing works with the shunt on the supply side, keeping the load referenced to ground
- External resistor gain-setting lets one device cover a wide range of full-scale current levels
- 2.7 V to 36 V common-mode range covers common battery and industrial bus voltages
- -40°C to +125°C extended-temperature rating suits automotive-adjacent and outdoor equipment
- 5-pin SOT-23 package minimizes footprint for space-constrained current-monitoring designs
- Analog current output integrates easily with an external resistor for a simple voltage readout
