I want to know when the valid data is ready after power up of AD7414.
My problem is when I read a tempurature data after 50msec, I got a garbage data. After 900msec, I can get corret one.

I want to know when the valid data is ready after power up of AD7414.

I am a member of HughK's team.
After power-on, I perform I2C initialization. Then, after a delay of 50mS, the initial temperature information is read. In some cases, this data is read as a value higher than 40 degrees compared to the current temperature. After about 800~900mS, the normal temperature is read. I am using more than 2,000, and there is a high probability that the initial data is read as incorrect as above. (Example: The value of 70 degrees is read at first, and the value of 30 degrees is read after 800mS.)
It also occurs irregularly every time power is applied to a single AD7414.
Hi, HughK ; Manbokdang .
Here is what the product owner said, "The datasheet says the data update rate is 800ms typically, so 50ms is too fast."
