The INA28x-Q1 family of voltage output current-sensing amplifiers are specifically designed to accurately measure voltages developed across current-sensing resistors on common-mode voltages that far exceed the supply voltage powering the devices. This family features a common-mode range that extends 14 V less than the negative supply rail, as well as up to 80 V, allowing for either low-side or high-side current sensing while the device is powered from supply voltages as low as 2.7 V.

The zero-drift topology enables high-precision measurements with maximum input offset voltages as low as 70 µV with a maximum temperature contribution of 1.5 µV/°C over the full temperature range of –40°C to 125°C.
