The product supports 36V, bidirectional, ultra-high-precision, low-side high-side, I2C output current power monitor with alarm function

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

                          Features and advantages

• The single-chip solution with I2C interface supports current, voltage and power measurement. It can simplify circuit board design without external multiplexers or ADCs, and cope with layout limitations;• Industry accuracy, with 10 uV offset voltage and 0.1% gain error, not only can achieve higher accuracy at low current, but also can use smaller shunt resistors, which can reduce I*R loss;• Independently programmable conversion time and sampling averaging technology can not only simplify the customization of the speed requirements of each system, but also reduce the requirements for software and memory;• 420 uA quiescent current and 2 uA shutdown current support high-efficiency work. Even if the INA226 integrates ADC and power multiplexer, the power consumption is 3.5% lower than the discrete solutions of similar competitive products;• 140 dB common mode rejection ratio (CMRR) and 36 V common mode voltage (CMV) ensure little or no change in offset voltage over the entire operating range, simplifying error analysis.
