ADS131E08 - Need Similar part with interal Buffer

Other Parts Discussed in Thread: ADS131E08

Hi Team,

As you know in ADS131E08, the data in DOUT register will be lost, if not read back before the next sample data is available. One of my Customer requires a buffer to store the sampled data and send again. Is there any alternate available for the part with similar specs and having a buffer ? They will re the start / interrupt command and Direct memory access (DMA).

Regards,

Hi Praveen,

How deep of a buffer would you like to see in a device like the ADS131E08? Is this an issue where they simply don't have enough time to react to the DRDY signal?

Hi Tom,

They require a buffer which can store at least 130 samples. Yes they don't have enough time to react to the DRDY Signal.

Thanks and Regards,
Praveen
