Product Description

With an offset voltage of 10 microvolts (uV) and a gain error of 0.1%, the INA226 is 10 times more accurate than its industry-leading competitors. The device is a complete 16-bit single-chip solution that provides fully programmable measurements of current, voltage, and power for digital I2C interfaces. The INA226 offers great advantages to designers of servers, telecommunications equipment, computers, power management equipment, and test equipment to meet their power measurement needs.

Main features and advantages
Single-chip solutions with I2C interface support current, voltage, and power supply measurements, simplifying board design and addressing layout limitations without external multiplexers or ADCs;
• Industry accuracy, with 10 uV offset voltage and 0.1% gain error, not only for higher accuracy at low current, but also for smaller shunt resistors to reduce I*R losses;
• Independent programmable conversion time and sample-averaging technologies simplify the customization of speed requirements for each system and reduce the need for software and memory;
• 420 uA static current and 2 uA turn-off current support efficient operation, even though the INA226 integrates ADC and power multiplexer, power consumption is 3.5% lower than competing discrete solutions;
