Texas Instruments INA290 Ultra-Precise Current Sense Amplifiers can measure voltage drops across shunt resistors over a wide common-mode range from 2.7V to 120V. It is in a highly space-efficient SC-70 package with a PCB footprint of only 2.0mm × 2.1mm. The ultra-precise current measurement accuracy is achieved thanks to the combination of an ultra-low offset voltage of ±12µV (maximum), a small gain error of ±0.1% (maximum), and a high DC CMRR of 160dB (typical). The INA290 is not only designed for DC current measurement but also high-speed applications (like fast overcurrent protection, for example) with high bandwidth of 1MHz (at a gain of 20V/V) and an 85dB AC CMRR (at 50kHz). The INA290 operates from a single 2.7V to 20V supply and draws a 370µA supply current (typical).
