INA226 IIC Current, voltage and power measurement sensor

Characteristics:

With I2C interface of single-chip solutions to support current, voltage and power measurement, to simplify the need for external multiplexer or ADC circuit board design, to design limitations;

Industry the highest precision, with a modest 0.1% uV maximum offset voltage and maximum gain error, it can not only implement higher precision in low power flow, but also can use a smaller shunt resistor, thus which can reduce I*R loss; Independent programmable conversion time and sample averaging technique can not only simplify the speed requirement of each system customization, but also reduce the demand for software and storage; The largest static current uA 420 and uA breaking current of brand 2 support efficient work, even if the integrated INA226 ADC and power multiplexer, power consumption and discrete solution of 3.5% lower than the products similar from the competition; 140 dB, common mode rejection ratio (CMRR) and common mode voltage (CMV) of 36 V within the scope of work to ensure little or no change in offset voltage, which can simplify error analysis.
