Texas Instruments' INA199 series of voltage output current shunt monitors can sense drops across shunts at common-mode voltages from –0.3 to 26 V, independent of the supply voltage. Three fixed gains are available: 50 V/V, 100 V/V, and 200 V/V. The low offset of the Zerø-Drift architecture enables current sensing with maximum drops across the shunt as low as 10 mV full-scale.

These devices operate from a single +2.7 to +26 V power supply, drawing a maximum of 100 µA of supply current. All versions are specified from –40°C to +105°C, and offered in both SC70 and thin QFN-10 packages.
