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 0
V to +28 V, with the device powered from a single
+2.7 V to +5.5 V supply, drawing 330 μA (typical) of
supply current. The INA230 is specified over the
operating temperature range of 40°C to +125°C.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not implied.
(2) VIN+ and VINmay have a differential voltage of 30 V to +30 V; however, the voltage at these pins must not exceed the range 0.3 V to
+30 V.
