What is this?
INA226 IIC I2C bidirectional current monitoring sensor is a complete 16-bit single chip that provides fully programmable measurements of current, voltage, and power for digital I2C interfaces. INA226 can bring advantages to telecommunications equipment, computers, power management, and test equipment, and can accurately measure power measurements.

What will I get?

Maximum gain error: 0.1%
Maximum offset voltage: 10 μV offset
Operating voltage is 2.7V ~ 5.5V
Measurement voltage: DC 0V~36V
Size: 20.5mmx19.4mm/0.81x0.76 inch(L*W)
Package Contains: 5 Sets x INA226 IIC I2C bidirectional current monitoring sensor

Are there any advantages of the product?
Not only can it achieve higher accuracy at low current, but it can also use smaller shunt resistors to reduce I*R losses;
420 uA maximum quiescent current and 2 uA maximum shutdown current support efficient operation. Even though the INA226 integrates ADC and power, the power consumption is 3.5% lower than the discrete solution of similar products;
140 dB common mode reject ratio and 36 V common mode voltage can ensure little or no change in offset voltage over the entire operating range, which can simplify error analysis
INA226 current voltage sensor has an alarm function,when the current or voltage exceeds the set range, the alarm pin will be triggered to warn.

How to use it?
INA226 is a current shunt and power monitor with I2C interface. Can monitor shunt voltage drop and bus supply voltage. Programmable calibration value, conversion time and average value, combined with internal multiplier, can directly read current and power.

What should I notice?
Ensure that the INA226 is provided with the appropriate supply voltage to ensure its normal operation
