INA228-Q1: Ask the difference between INA228 &I INA233

Part Number: INA228-Q1
Other Parts Discussed in Thread: INA228, INA233, INA229

Hi TI,

Currently we're using INA233 in our design, and considering taking INA228 in to be the alternatives of INA233, so here I'd like to check following things:

1. What's the major difference between these two products? Is it more precise for INA228 than INA233?

2. Is there any potential issues we might have if we take INA228 to replace INA233, like some function which is not included in INA228?

Also,except for INA228, is there any similar you recommend to replace INA233? we will need it having better performance than INA228, thanks in advance!

Tim

  • Hello Tim,

    1.Major differences can usually be seen on the first page but for detailed differences you will need to go through the datasheet.  The INA228 has better accuracy and precision and can be seen in the front page for comparisons.

    2.There are some differences but I think the INA228 has more functions available.  The calculations for the power calculations are different.  

    The INA228(I2C) and the INA229(SPI) are the best performance digital designs available and they are newly released.
