Overview
Description
The INA139 and INA169 are high-side, unipolar, current shunt monitors. They offer a wide input common-mode voltage range, high speed, low quiescent current, and a compact SOT23 package. These features make them suitable for various applications.
The devices convert a differential input voltage to a current output, which is then converted back to a voltage using an external load resistor. This allows for gain adjustment from 1 to over 100.

Features
High-side measurement
Wide supply and common-mode range:
INA139: 2.7V to 40V
INA169: 2.7V to 60V
Independent supply and input common-mode voltages
Single resistor gain set
Low quiescent current (60μA typ)
SOT23-5 package

Applications
Current shunt measurement in automotive, telephone, and computer systems
Portable and battery-backup systems
Battery chargers
Power management
Cell phones
Precision current sources
