NCS199A1: Current Sense Amplifier, 1.5% Max. Gain Error, Bi-Directional Zero-Drift, -0.3V to 26V CMIVR
The NCS199A1, NCS199A2 and NCS199A3 are voltage output
current shunt monitors that can measure voltage across shunts at
common−mode 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.
The low offset of the zero−drift architecture enables current sensing
with maximum drops across the shunt as low as 10 mV full−scale.
The devices can operate from a single +2.7 V to +26 V power
supply, drawing a maximum of 100µA of supply current. All versions
are specified over the extended operating temperature range (–40°C to
+125°C).
