SparkFun Current Sensor Breakout - INA169

The SparkFun Current Sensor Breakout - INA169 is a unique high-side current monitor designed for precise measurements. This product uses a shunt resistor placed on the positive power rail, and the INA169 measures the voltage drop across this resistor. The INA169 then provides a small current based on the measured voltage drop. By placing a resistor from the output of the INA169 to the ground, the voltage at the output can be effectively measured.

One of the key features of the INA169 is its independent input common-mode and power supply voltages. These can range from 2.7V to 60V, offering a wide spectrum of voltage measurements. Additionally, the quiescent (sleep) current is a mere 60uA, ensuring energy efficiency even when the device is not in active use.

Usage of the SparkFun Current Sensor Breakout - INA169 is not limited to professionals only. Even hobbyists and students can utilize this device for their projects. Whether it's for creating a power consumption monitor, a battery charger, or an overcurrent protection device, the INA169 is a reliable tool for precise current measurements.

What sets the INA169 apart is its high-side measurement capability. This feature allows for safer and more accurate measurements as it eliminates the risk of short circuiting to ground. Also, the wide common-mode voltage range makes it suitable for various applications, from low-voltage to high-voltage systems.

The SparkFun Current Sensor Breakout - INA169 comes with comprehensive documentation including a schematic, Eagle files, a datasheet, a hookup guide, and a GitHub repository. This ensures users have all the necessary resources at their disposal to fully utilize the INA169.
