Part Number: ADS1247 Other Parts Discussed in Thread: TIPD152 , , TIPD120 Hello,
I just had quite a few boards made using the ADS1247. Referring to the TIPD152 reference design, I didn't ground the CLK input. (Didn't realize that the data sheet says to ground…
Respected Mr.Collin,
Thanks for replying us, i bring these solutions to my senior engg. but due to some company policy i want sample for TIPD120 , TIPD152
to check its accuracy level.
>> Can your company has free sample policy? if so…
Markus,
Generally, we're here to help answer questions about using our devices. Doing a complete reference design isn't something that we normally do here in the forum. However, there are a few reference designs that you can look over based on the ADS1248…

1) What is your desired differential input signal range (according to the full scale temp range in your application using the PT-100)?
I measuring a PT1000 from 603ohm to 1565ohm, with 700uA IB it translate to 0.4221-1.0955 Volts, with 1K…
Ankit,
I'm glad you were able to get the measurement to work. I figured you had a simple setup error and that you were basically measuring a zero input.
I was just answering a similar about the calibration in another post. The ADS1248 is factory…

Harish,
I assume that you mean "thermocouple" and not "thermonuclear".
I wouldn't use the PCM1808 for this application. It's generally an audio adc and used for more ac applications. For the ADS7813, you could use it and it would…
Other Parts Discussed in Thread: ADS1248 , TIPD120 , TPD4E110 , ADS1262 , ADS1220 Hi all,
We have designed a RTD measurement system, using 24 bit ADC ADS1248 from TI.
We are measuring different RTD types like Pt100, Ni100, Pt200 , Pt1000 etc. Maximum resistance we need to measure is arou…
Hi Rob,
Usually the RTD max current refers to maximum current through the RTD element, but this question is better asked of the RTD manufacturer. You do not need to use the maximum current. There is self heating that will occur due to the current flowing…
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 case…
