The INA169 is a “high-side current monitor,” which means that you place a resistor (a “shunt resistor”) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a small current based on the measured voltage drop. If you place a
esistor from the output of the INA169 to ground, you can measure the voltage at the output.
Input common-mode and power supply voltages are independent and can range from 2.7V to 60V on the INA169 and quiescent (sleep) current is only 60uA.
