INA226 in INA219 / INA226 Current Sensors Family
The INA226 family from Texas Instruments consists of high-precision current, voltage, and power monitors with an I2C-compatible interface. Designed for both high-side and low-side sensing, these digital power monitors provide 16-bit resolution to ensure accurate measurements across a wide bus voltage range from 0V to 36V. The integrated power accumulator and programmable conversion times make it a standard choice for engineers requiring high-accuracy power telemetry in complex power distribution systems and battery-powered applications.
