3 Description

The INA230 is a current-shunt and power monitor

with an I2C interface that features 16 programmable

addresses. The INA230 monitors both shunt voltage

drops 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 INA230 senses current on buses that vary from

0V to 36V, with the device powered from a single

2.7V to 5.5V supply, drawing 330μA (typical) of supply

current. The INA230 is specified over the operating

temperature range of –40°C to +125°C.
