Part Number: TIPD120 Other Parts Discussed in Thread: ADS124S08EVM , ADS124S08
Hi,
I am having a requirement of a RTD measurement system and found TIPD120 is more or less the same design I require. How could I get the TIPD120 ? Is there any sample…
Part Number: ADS1247EVM Other Parts Discussed in Thread: ADS1247 , TIPD120
Hi,
I am currently working with the ADS1247 EVM for an RTD measurement application.
I have modified the EVM circuit with reference of TIPD120 Design files and the modifications…
Other Parts Discussed in Thread: TIPD120 Can someone provide the link to the schematic of TIPD120?
The links on the TI website seem broken.

Hello Suresha,
Many systems specify accuracy/error in terms of %FSR which means the accuracy in percent of the full-scale range. We are going to update some things about TIPD120 and one of them is to specify the accuracy in degrees Celcius to make it…
Hello,
Please review the reference designs shown below and they'll provide two methods with the ADS1247. All of the required calculations are included and explained.

Hi Vincent,
I am not aware of a pspice model for the ADS1246. In fact I am not aware of any model for TI precision delta-sigma ADCs. There was a simulation done within TIPD120 that used a macro model to simulate the response of the ADC up to the ADC…
Hello David,
Here are some answers to your questions about the TIPD120 circuit.
The implementation uses 2 stages in order to "allow the high side current source to accept a ground referenced input". Can you please elaborate regarding this consideration…
Hello Kutluk,
We have a TI Precision Design (TIPD120) that employs a common 3-wire Pt100 RTD. It is highly accurate, doesn't require cold junction compensation, and has a temperature range of -200 C to +850 C. You can view the information here:

Hi Pattan
that depends on your circuit implementation and ADC configuration. The following reference design shows one possible solution for a 3-wire RTD measurement system and describes how to calculate the RTD resistance.
Please let us know in…
