Dear Angel,
like always thanks a lot for your reply and support about your products. Thanks for sharing informations and AN names.
From a surge (IEC61000-4-5) standard point of view, it seems that the ads1220 is ready until 2kV which seems normal as it…
Part Number: ADS1220 Tool/software: Hello e2e,
Is it possible to connect 2 pcs 3-Wire PT100 in one ADS1220? and do you have any recommendation in circuits?
Thanks.

Hi Sai,
You mentioned that when you write to a register and do a read back data appears to be right shifted. This is likely the same issue when you read ADC conversion data, since you mentioned there is a specific offset in the data. There is probably…
Part Number: ADS1220 Tool/software: Hi
As for the input impedance of ADS1220, I did not find this parameter in the specification. Now I need to use ADS1220 to detect PT1000. I am going to add a follower in the input side, which I think is necessary,thanks…
Part Number: ADS1220 Other Parts Discussed in Thread: ADS1246 , Tool/software: Hi TI expert
I'm looking for an ADC to fit the following specifications: It has to measure a thermistor from a range of -40degC to 80 degC with a precision of 0.001 degC…
Part Number: ADS1220 Tool/software: Hi ,
I am try to make universal input device like ( 4-20 input ,Thermocouple K type ,J type ,RTD 2-wire , RTD 3-wire ,RTD-4 wire )
can any one suggest me circuit diagram for universal input .using ADS1220 or any other…
Hi Angel Rodriguez de San Miguel Bermudez ,
I want to express my gratitude for your help and guidance. I’ve realized what my mistake was, and I’ve finally resolved the issue with the ADS1220. It’s working perfectly now!
I truly appreciate…
Hi,
I recreated a 2-wire and 3-wire RTD setup on the ADS1220 EVM.
I used a 100 Ohm resistor for the 2-wire RTD, and the reference resistor on the EVM was 2.4kOhms.
Gain = 1, PGA disabled, 175SPS DR.
The followings are the results for when the IDAC was…
Part Number: ADS1220 Tool/software: Hi DC team, What is our alternative to AD7793BRUZ? Crossref suggest different devices depending on the reel size of ADI !?? AD7793BRUZ -> ADS1220IRVAR
AD7793BRUZ-REEL -> ADS1219IRTER

Part Number: ADS1220 Tool/software: Hello,
Looking at section 9.2.2 of the datasheet details an example application with a 3 wire RTD. What would be the consequence of removing Rf4 and Ccm4 in the reference design? would that effect noise performance…
