INA281 Datasheet (Texas Instruments) - 1.3-MHz Current-Sense Amplifier

INA281, 1.3-MHz Current-Sense Amplifier

The INA281 is a high-precision current sense amplifier that can measure voltage drops across shunt resistors over a wide common-mode range from *4 V to 110 V.

The negative common-mode voltage allows the device to operate below ground, thus accommodating precise measurement of recirculating c
