INA290 Description
The INA290 is an ultra-precise current sense amplifier that can measure voltage drops across shunt resistors over a wide mon-mode range from 2.7 V to 120 V. It is in a highly space-efficient SC-70 package with a PCB footprint of only 2.0 mm × 2.1 mm. The ultra-precise current measurement accuracy is achieved thanks to the bination of an ultra-low offset voltage of ±12 µV (maximum), a small gain error of ±0.1%...
