INA226AIDGST

The INA226AIDGST is a Current Shunt and Power Monitor with an I²C™- or SMBUS-compatible interface. The device monitors both a shunt voltage drop and bus supply voltage. Programmable calibration value, conversion times and averaging, combined with an internal multiplier, enable direct readouts of current in amperes and power in watts. The INA226AIDGST senses current on common-mode bus voltages that can vary from 0 to 36V, independent of the supply voltage. The device operates from a single 2.7 to 5.5V supply, drawing a typical of 330µA of supply current. The device is specified over the operating temperature range between -40°C and 125°C and features up to 16 programmable addresses on the I²C-compatible interface.
