INA139  
INA169  
SBOS181D DECEMBER 2000 REVISED NOVEMBER 2005  
High-Side Measurement  
CURRENT SHUNT MONITOR  
DESCRIPTION  
FEATURES  
COMPLETE UNIPOLAR HIGH-SIDE  
CURRENT MEASUREMENT CIRCUIT  
WIDE SUPPLY AND COMMON-MODE RANGE  
INA139: 2.7V to 40V  
The INA139 and INA169 are high-side, unipolar, current  
shunt monitors. Wide input common-mode voltage range,  
high-speed, low quiescent current, and tiny SOT23 packag-  
ing enable use in a variety of applications.  
INA169: 2.7V to 60V  
INDEPENDENT SUPPLY AND INPUT COMMON-  
MODE VOLTAGES  
SINGLE RESISTOR GAIN SET  
LOW QUIESCENT CURRENT (60µA typ)  
SOT23-5 PACKAGE  
Input common-mode and power-supply voltages are inde-  
pendent and can range from 2.7V to 40V for the INA139 and  
2.7V to 60V for the INA169. Quiescent current is only 60µA,  
which permits connecting the power supply to either side of  
the current measurement shunt with minimal error.  
The device converts a differential input voltage to a current  
output. This current is converted back to a voltage with an  
external load resistor that sets any gain from 1 to over 100.  
Although designed for current shunt measurement, the cir-  
cuit invites creative applications in measurement and level  
shifting.  
APPLICATIONS  
CURRENT SHUNT MEASUREMENT:  
Automotive, Telephone, Computers  
PORTABLE AND BATTERY-BACKUP  
SYSTEMS  
Both the INA139 and INA169 are available in SOT23-5  
packages and are specified for the –40°C to +85°C industrial  
temperature range.
