ADS1292R: Datasheet discrepancy

Part Number: ADS1292R


Hi Team,

We have a question about ADS1292R need your help.

We are using respiration function on channel 1. About the capacitor between PGA1N and PGA1P, seems there 2 different values in the datasheet.

In page 67: it says 47nF.

But in page 23, it is 4.7nF.

In our understanding, it should be 47nF for respiration,  I guess this 4.7nF is a typo, but we would need your confirmation.

Regards,

RJ

    Hi Ramon,

    Thanks for the E2E post. 

    Yes, you are correct on the typo on page 23. For respiration, the recommended external capacitors for CH1 PGA1P and PGA1N output pins should be 47nF (please refer to Figure 42). We will update the datasheet on the next revision cycle.

    Thanks
