DESCRIPTION
The INA199A1RSWR series of voltage output current shuntmonitors can sense drops across shunts at common-mode voltages from -0.3V to 26V, independent of the supply voltage. Three fixed gains are available:50V/V,100VV, and 200VV. The low offset of the Zero-Drift architecture enables current sensing with maximum drops across the shunt as low as 10mV full-scale.
These devices operate from a single +2.7V to +26V power supply, drawing a maximum of 100uA of supply current. All versions are specified from-40℃ to +105°℃, and offered in both SC70 and thin QFN-10 packages.
