The INA138NA/250G4 is a 36V, high-side, Current Output Current Shunt Monitor, laser trimmed for very low offset voltage (50μV), drift (0.5μV/°C) and high common-mode rejection (120dB at G >=100). It operates with power supplies as low as ±2.25V and quiescent current is only 700μA - ideal for battery-operated systems. Internal input protection can withstand up to ±40V without damage. The INA138NA/250G4 is high-side, unipolar, current shunt monitors. Wide input common-mode voltage range, low quiescent current. Input common-mode and power-supply voltages are independent and can range from 2.7 to 36V for the INA138NA/250G4. Quiescent current is only 25μA, which permits connecting the power supply to either side of the current measurement shunt with minimal error. The device converts a differential input voltage to a current output. This current is converted back to a voltage with an external load resistor that sets any gain from 1 to over 100.
