INAx290 2.7-V to 120-V, 1.1-MHz, Ultra-Precise, Current-Sense Amplifier  
1 Features  
3 Description  
Wide common-mode voltage:  
– Operational voltage: 2.7 V to 120 V  
– Survival voltage: −20 V to +122 V  
Excellent CMRR:  
– 160-dB DC  
– 85-dB AC at 50 kHz  
Accuracy  
The INAx290 is an ultra-precise, current-sense  
amplifier that can measure voltage drops across shunt  
resistors over a wide common-mode range from 2.7  
V to 120 V. The ultra-precise current measurement  
accuracy is achieved thanks to the combination of an  
ultra-low offset voltage of ±12 µV (maximum), a small  
gain error of ±0.1% (maximum), and a high DC CMRR  
of 160 dB (typical). The INAx290 is not only designed  
for DC current measurement, but also for high-speed  
applications (such as fast overcurrent protection, for  
example) with a high bandwidth of 1.1 MHz (at gain of  
20 V/V) and an 85-dB AC CMRR (at 50 kHz).  
– Gain:  
Gain error: ±0.1% (maximum)  
Gain drift: ±5 ppm/°C (maximum)  
– Offset:  
Offset voltage: ±12 µV (maximum)  
Offset drift: ±0.2 µV/°C (maximum)  
The INAx290 provides the capability to make ultra-  
precise current measurements by sensing the voltage  
drop across a shunt resistor over a wide common-  
mode range from 2.7 V to 120 V. The INAx290  
devices come in highly space-efficient packages.  
The single-channel INA290 device is featured in the  
SC-70 package, the dual-channel INA2290 device  
is available in the MSOP-8 package, and the quad-  
channel INA4290 device is available in the 4 mm x 4  
mm QFN package.  
Available gains:  
– A1 devices: 20 V/V  
– A2 devices: 50 V/V  
– A3 devices: 100 V/V  
– A4 devices: 200 V/V  
– A5 devices: 500 V/V  
High bandwidth: 1.1 MHz  
Slew rate: 2 V/µs  
Quiescent current: 370 µA (per channel)  
The INAx290 operates from a single 2.7-V to 20-V  
supply with the single channel device only drawing  
370-µA supply current per channel (typical). The  
devices are available with five gain options: 20 V/V,  
50 V/V, 100 V/V, 200 V/V, and 500 V/V. The low offset  
of the zero-drift architecture enables current sensing  
with low ohmic shunts as specified over the extended  
operating temperature range (−40°C to +125°C).
