8 Detailed Description
8.1 Overview
The INA210-INA215 are 26-V, common-mode, zero-drift topology, current-sensing amplifiers that can be used in
both low-side and high-side configurations. These specially-designed, current-sensing amplifiers are able to
accurately measure voltages developed across current-sensing resistors on common-mode voltages that far
exceed the supply voltage powering the device. Current can be measured on input voltage rails as high as 26 V
while the device can be 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
35 µV with a maximum temperature contribution of 0.5 µV/°C over the full temperature range of –40°C to 125°C.
