INA230AIRGTR Description

The INA230AIRGTR is a current shunt and power monitor with an I2C interface that features 16 programmable addresses. The Current Sense Amplifier INA230AIRGTR monitors both shunt voltage drops and bus supply voltage. Direct readouts of current in amperes and power in watts are possible thanks to programmable calibration values, conversion times, and averaging, as well as an inbuilt multiplier.

The INA230AIRGTR senses are current on buses that vary from 0V to 36V, with the device powered from a single 2.7-V to 5.5-V supply, drawing 330 μA (typical) of supply current. The INA230AIRGTR is specified over the operating temperature range of –40°C to +125°C.
