Description

The device can be operated by a power supply as low as 1.8V (± 0.9V) with a quiescent current of only 50 μA, so it is very suitable for battery-powered systems. The INA333 device uses automatic calibration technology to ensure excellent accuracy in the extended industrial temperature range, while also providing ultra-low noise density (50nV/√Hz) that extends down to DC.
