SPARKFUN ELECTRONICS - INA169 Current Sensor Breakout Board
Precision current sensing breakout board (2.7–60V DC) for battery monitoring & power analysis. Measures low current via high-side voltage drop.
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.
