FEATURES  
DESCRIPTION  
The INA223 is a voltage-output device that monitors  
the current, bus voltage, and power of a supply line  
by sensing a voltage drop across a shunt at common-  
mode voltages from 0 V to 26 V. The common-mode  
voltage range is independent of the supply voltage.  
The low offset of the Zerø-Drift architecture enables  
current sensing with maximum drops across the  
shunt as low as 10 mV, full-scale.

The INA223 includes a two-wire interface used for  
adjusting the configuration settings of the device. The  
interface is used to control the signal (current shunt  
voltage, bus voltage, or power) that is directed to the  
device output. Multiple gain and attenuation settings  
can be programmed through the two-wire interface to  
allow for application-specific configurations. The  
programmable gain feature also allows the device to  
be operated over a much wider dynamic current load  
range without having to switch the sensing element  
used.

Quiescent Current: 250 µA (Max)

A shutdown feature is available to disable the device  
and effectively disconnect it from the shunt resistor  
and supply voltage, thus reducing the drain on the  
battery.  
APPLICATIONS  
The INA223 operates from a single +2.7-V to +5.5-V  
supply, drawing a maximum supply current of 250 µA.  
It is specified over the extended temperature range of  
–40°C to +105°C, and is offered in an SON-10  
package.
