The INA226 Module is a high-precision current, voltage, and power monitoring sensor designed for I²C or SMBus communication. It leverages Texas Instruments’ INA226 integrated circuit to provide accurate measurements in various applications, including battery management, power supplies, and energy monitoring systems. The maximum offset voltage of the INA226 is 10 microvolts (uV), the maximum gain error is 0.1%, and the accuracy is 10 times higher than the industry-leading competitors. The device is a complete 16-bit single-chip solution that provides fully programmable measurements of current, voltage, and power for digital I2C interfaces. The INA226 can bring great advantages to designers of servers, telecommunications equipment, computers, power management equipment, and test equipment to fully meet their needs for accurate power measurement.
