Hi all,

I need 3 information regarding INA223 IC.

1. what is the sampling data rate of this INA223 IC?

Does it give measured current details continuously or with some intervals.

2.What is purpose of "VOUT" pin in this INA223 IC.

3. We receive current measurement signals through I2C bus?

Kindly some one reply to my queries,it would be helpful for my project.

Thanks & Regards

Hello Nikhil,

There is no sampling as this device does not have an ADC. If you are looking for one with an ADC we do have our new INA228 device.
After configuring the device gain options the Vout is an analog power calculation. There is an example in the datasheet.
This device does not have measurement register and the register is available is only for configuration. This device does not have an ADC and is an analog output.

Dear Mr.JAVIER,

Thanks for your valuable reply.

-> I would like to know weather i will be getting "output current measurement value" continuously or with some time period intervals from INA223?

Please let me know the same.

Regards

NIKHIL

Hello Nikhil,

The output is a power calculation, not a current measurement, and it is an analog input/output limited by the bandwidth. The bandwidth is a function of the gain selected as seen in the datasheet. Image below.
