INA226 Voltage Current And Power Monitor

Product Information:

The INA226 has an offset voltage of 10 microvolts (uV) and a gain error of 0.1%, with an accuracy 10 times higher than industry-leading competitive products. This device is a complete 16 bit single-chip solution that can provide comprehensive programmable measurements of current, voltage, and power supply for digital I2C interfaces. INA226 can bring great advantages to designers of servers, telecommunications equipment, computers, power management equipment, and testing equipment, fully meeting their needs for power measurement.

Main features and advantages:

A single chip solution with I2C interface supports current, voltage, and power measurement, simplifying circuit board design without the need for external multiplexers or ADCs, and addressing layout limitations;

Industry precision, with a 10 uV offset voltage and 0.1% gain error, not only achieving higher accuracy at low currents, but also using smaller shunt resistors to reduce I * R losses;

Independent programmable conversion time and sampling average technology can not only simplify the customization of speed requirements for each system, but also reduce the demand for software and memory;

420 uA static current and 2 uA off current support efficient operation, even if INA226 integrates ADC and power multiplexer, the power consumption is 3.5% lower than the split type solution of similar competitive products;

The 140 dB common mode rejection ratio (CMRR) and 36 V common mode voltage (CMV) ensure minimal or no change in offset voltage throughout the entire operating range, simplifying error analysis.
