Voltage Output, Unidirectional Measurement  
Current-Shunt Monitor  
FEATURES  
DESCRIPTION  
WIDE COMMON-MODE RANGE: –16V to +80V  
The INA270 and INA271 family of current-shunt  
monitors with voltage output can sense drops across  
current shunts at common-mode voltages from –16V  
to +80V, independent of the supply voltage. The  
INA270 and INA271 pinouts readily enable filtering.  
CMRR: 120dB  
ACCURACY:  
±2.5mV offset (max)  
±1% gain error (max)  
20µV/°C offset drift (max)  
55ppm/°C gain drift (max)  
The INA270 and INA271 are available with two  
output voltage scales: 14V/V and 20V/V. The 130kHz  
bandwidth simplifies use in current-control loops.  
BANDWIDTH: Up to 130kHz  
The INA270 and INA271 operate from a single +2.7V  
to +18V supply, drawing a maximum of 900µA of  
supply current. They are specified over the extended  
operating temperature range of –40°C to +125°C and  
are offered in an SO-8 package.  
TWO TRANSFER FUNCTIONS AVAILABLE:  
14V/V (INA270)  
20V/V (INA271)  
QUIESCENT CURRENT: 900µA (max)  
POWER SUPPLY: +2.7V to +18V
