INA226 Voltage Current Power Monitor Alarm Function 36V Bidirectional I2C Module

The INA226 has a maximum 0ffset voltage of 10 microvolts (uV), a maximum gain error of 0.1%, and is 10 times more accurate than industry-leading competitors. The device is a complete 16-bit single-chip solution that provides fully programmable measurements of current, voltage, and power for a digital I2C interface. The INA226 brings great advantages to designers of servers, telecommunications equipment, computers, power management equipment, and test equipment, meeting their needs for accurate power measurements.

• Single-chip solution with I2C interface supports current, voltage, and power measurements, simplifying board design and addressing layout limitations without the need for external multiplexers or ADCs;

• Industry's highest accuracy with 10 uV maximum 0ffset voltage and 0.1% maximum gain error, enabling higher accuracy at lower currents and using smaller shunt resistors for lower I*R losses;

• Independently programmable conversion time and sample averaging technology not only simplifies the customization of each system's speed requirements, but also reduces software and memory requirements;

• 420 uA maximum quiescent current and 2 uA maximum shutdown current support efficient operation, even with the integrated ADC and power multiplexer, the INA226 consumes 3.5% less power than competing discrete solution;

• 140 dB common mode rejection ratio (CMRR) and 36 V common mode voltage (CMV) ensure little or no change in 0ffset voltage over the entire operating range, simplifying error analysis.
