INA290 Datasheet (Texas Instruments) - Ultra-Precise Current-Sense Amplifier

INA290, Ultra-Precise Current-Sense Amplifier

The INA290 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.

It is in a highly space-efficient SC-70 package with a PCB footprint of only 2.0 mm × 2.1 mm.
