SPARKFUN ELECTRONICS - INA169 Current Sensor Breakout Board

The SPARKFUN ELECTRONICS INA169 Current Sensor Breakout Board is designed for precise current measurement applications. Built around the INA169 high-side current monitor IC, this board is ideal for monitoring current draw or low currents in electronic components with high precision and ease of integration.

Key Features:

• Easy to use—simply place a resistor on the positive power rail to measure voltage drop.
• The INA169 outputs a small current proportional to the measured voltage drop, which can then be converted to a voltage reading with an external resistor.
• Independent input common-mode and power supply voltages ranging from 2.7V to 60V, making it versatile for various electronic applications.
• Compact breakout board format for straightforward prototyping and testing.

Important Considerations:

• DC measurement only—cannot measure AC current.
• Polarity-sensitive: The VIN+ pin must always be at a higher potential than the VIN- pin.

Applications: Suitable for battery monitoring, power consumption analysis, and precision current sensing in embedded electronics projects.
