The Adafruit INA169 Analog DC Current Sensor Breakout is designed for hobbyists, engineers, and students who need precise, high-side current monitoring for electronic projects. It excels at measuring DC current draw up to 5A without interfering with your circuit's ground reference, though users should note that it requires manual voltage-to-current calculations based on the analog output.

No, the INA169 is specifically designed for DC current measurement.
The board is rated for 5A of continuous current.
Using the stock 10k resistor, the output is 1V per Amp. Simply measure the output voltage to determine the current in Amps.
Yes, but ensure the output voltage of the sensor does not exceed the maximum input voltage allowed by your microcontroller's ADC pin.
The 0.1 Ohm sense resistor is fixed; however, you can modify the gain by changing the load resistor.
Check that the load is correctly wired in series with the V+ and V- pins, and verify the sensor has a shared ground with your microcontroller.
Ensure your connections are secure and use short wires to minimize EMI interference. If using a high-frequency switching regulator, add a small capacitor on the output pin to smooth the signal.
To begin, solder the included 5-pin header onto the breakout board for breadboard mounting. Connect the V+ pin to the positive side of your power supply and the V- pin to the load's positive input. Ensure the ground of your sensor board is connected to the common ground of your system.
