GY-169 INA169 Current Sensor Module
Product Description
The GY-169 INA169 Current Sensor Module is a compact high-side current monitoring module designed to measure DC current accurately without disturbing the system ground path. Based on the INA169 current-sense amplifier, it converts the voltage developed across a shunt resistor into an analog voltage proportional to the measured current.
Its high-side sensing configuration makes it suitable for battery monitoring, power supplies, motor control, automotive systems, and DIY power measurement projects.
High-Side Current Sensing
Unlike low-side current sensing, the INA169 monitors current on the positive power rail, helping maintain a common and stable ground connection for the rest of the system.
This makes the module useful in applications where maintaining ground integrity is important, including battery chargers, motor controllers, power supplies, and audio-related systems.
Wide Voltage Support
The module supports a wide common-mode voltage range of 2.7V to 60V, allowing it to be used with various low- and high-voltage DC systems.
Its wide operating temperature range of -40°C to +85°C also makes it suitable for a variety of embedded and industrial monitoring applications.
Analog Output
The module provides an analog voltage output proportional to the measured current. This output can be connected to an ADC input of a microcontroller or data acquisition system for current monitoring and measurement.
