Required clarification about SAADC function with reference to Errata document

[RatheeshT]

Hi Team, 

I planned to have product with this nRF52832 chip and now development was getting stopped because of known issues on SAADC on this nRF52832 chip. When I am seeing the Errata document, it is listing out 6 issues on SAADC. 

Totally 5 Errata document has been released so far for nRF52832 board.

Below list of errors are available in this board for SAADC.

 

Document Name                                              Errata ID

nRF52832 Engineering A Errata  -              8-28-74-86

nRF52832 Engineering B Errata  -              74-86

nRF52832 Engineering C Errata  -              74-86-150-178

nRF52832 Rev 1 Errata               -              74-86-150-178

nRF52832 Rev 2 Errata                -              74-86-150-178

               

 Only two issues has been fixed till now and based on this I have below questions.

Q1. is this issue from Software side  or Hardware side ?

Q2. when it will be solved?

Q3. Can I continue this board for my sensor(ADC measurement) application?

Q4. Which series of board is not having issue like this?

Please give your valuable feedback to show progress on my development.

1. HW issue, mostly timing problems. 

2. Probably not for the nRF52832, these Erratas are not really a problem. They all got simple workarounds that does not impact the performance of the SAADC. 

3. Yes, absolutely!

4. I think they're fixed in nRF52840, nRF52810, and nRF52811.

Hi, 

Thanks for your quick reply.

-- If sample input is greater than 10us, there is no problem on Issue ID – 74,150,&174,..

is my understanding correct or please clarify it?

What do you mean by " If sample input is greater than 10us" ?
