INA139NA/3K
Brand: Texas Instruments
The INA139NA/3K is the 3000-piece tape-and-reel version of TI's high-side current-sense amplifier, sharing the same 2.7 V to 36 V common-mode range and external gain-resistor flexibility as the tube-packed INA139NA. It fits high-volume automated placement for battery, motor and industrial current-monitoring production lines.

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
- 3000-piece tape-and-reel packing suits high-volume pick-and-place production lines
- 5-pin SOT-23 package minimizes footprint for space-constrained current-monitoring designs
- -40°C to +125°C extended-temperature rating suits automotive-adjacent and outdoor equipment
