INA169 High Side DC 27V to 60V Current Sensor Breakout Module For Arduino

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 resistor 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. Introduction Have a project where you want to measure the current draw? Need to carefully monitor low current through an LED? The INA169 is the chip for you! 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 resistor from the output of the INA169 to ground, you can measure the voltage at the output. With some basic math, the output voltage gives you the current through the shunt resistor.
