SBOS781E March 2016 – May 2021 INA199-Q1
PRODUCTION DATA
The INA199-Q1 is a 26-V, common-mode, zero-drift topology, current-sensing amplifier that can be used in both low-side and high-side configurations. The device is a specially-designed, current-sensing amplifier that is able to accurately measure voltages developed across a current-sensing resistor 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 and 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 150 µV with a maximum temperature contribution of 0.5 µV/°C over the full temperature range of –40°C to +125°C.
