NCS199A1, NCS199A2, NCS199A3 Current-Shunt Monitor, Voltage Output, Bi-Directional Zero-Drift www.onsemi.com The NCS199A1, NCS199A2 and NCS199A3 are voltage output current shunt monitors that can measure voltage across shunts at commonmode voltages from 0.3 V to 26 V, independent of supply voltage. Three fixed gains are available: 50 V/V, 100 V/V or 200 V/V. SC706 SQ SUFFIX The low offset of the zerodrift architecture enables current sensing CASE 419B with maximum drops across the shunt as low as 10 mV fullscale. The devices can operate from a single +2.7 V to +26 V power supply, drawing a maximum of 100 A of supply current. All versions PIN CONNECTIONS are specified over the extended operating temperature range (40C to +125C).
