The INA226 has a maximum offset voltage of 10 microvolts (uV) with a maximum gain error of 0.1% and is 10 times more accurate than the industry's 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 brings great benefits to designers of servers, telecom equipment, computers, power management equipment, and test equipment to meet their demand for accurate power measurements.
Key Features and Benefits
- Single-chip solution with I2C interface supports current, voltage, and power measurements, simplifying board design and addressing layout constraints without the need for an external multiplexer or ADC;
- Industry's highest accuracy with 10 uV Maximum offset voltage and 0.1% maximum gain error for higher accuracy at low currents and smaller shunt resistors for reduced I*R losses;
- Independently programmable conversion time and sample averaging techniques Not only simplifies the customization of speed requirements for each system, but also reduces software and memory requirements;
- 420 uA maximum quiescent current and 2 uA maximum shutdown current for efficient operation, even with INA226 integrated ADC and power multiplexer Power consumption is also 3.5% lower than discrete solutions from competing products;
- 140 dB common-mode rejection ratio (CMRR) and 36 V common-mode voltage (CMV) ensure minimal or no change over the entire operating range The varying offset voltages simplify the error analysis.
