Part Number: ADS1248 Other Parts Discussed in Thread: STRIKE , Dear Bryan,
With reference to our previous discussions on this topic, I appreciate if you could clarify some information from the device datasheet:
The specified device input current (except…
Hi Chuck Wong,
Chuck Wong said: As we both can see, both ±2.5V voltages were impacted when the U1 and U8 goes bad. Do you have any insights as on why the ADS1248 is holding down their supplies to a bad level?
If the ADCs are holding down the supplies,…
Part Number: ADS1248 What's up TI,
We have used ADS1248 for many years with 1000 ohm 2 mV/V strain gauges, 2 mA constant current (1 mA x 2 in parallel) and 3.6VDC rails. Internal reference, 1 ksps. We have tens of thousands in the field with very…
Part Number: ADS124S08 Other Parts Discussed in Thread: ADS1248
Hello,
I have a thermopile sensor that gives min-max output between 0.134 mV and 178 mV. I used the ADS124S08 integration and gave the output of the thermopile directly to the ADC integration…
Part Number: ADS1248 Other Parts Discussed in Thread: OPA335 , ADS124S08 I have a photodiode sensor that gives a min-max output between 0.134 mV and 178 mV. I will amplify the output mV of this sensor using OPA335 and then give it to the ADS1248 ADC. The…
Part Number: ADS1248 Hello there,
I understand that this forum is not the right place for the subject matter, but we as a company has exhausted all our means in a goal to procure this part ADS1248IPWR for our products from all our approved list of suppliers…
Part Number: ADS1248
在使用28PIN的ADS1248芯片时,25脚DRDY引脚,在什么情况下会一直不出现低电平,目前有出现过因为等待DRDY引脚拉低电平,导致单片机陷入死循环的问题,问题是极低概率出现,下图是ADS1248的电路图,是按照规格书的建议连接的,请帮忙给出一些排查问题的建议,非常感谢~
Part Number: ADS1248 An error occurs after running for a period of time, There is no problem for us to replace the same product of other batches, there is something wrong with marking 74K, and there is no problem with marking 78K. Please help to confirm…
Part Number: ADS1248 In our configuration:
START line is held high
Using SPI commands (SYNC, SLEEP, WAKEUP) rather than IO lines for control.
SDATAC command has been given to disable continuous conversions
Using DRDY- interrupts to signal conversion…
Part Number: ADS1248 Dear team,
How to do compatible design in ADS1248 for both PT1000 and NTC design? Our recommend circuit is for PT1000, but I can not figure out how to do compatible for NTC. The precision is required in 2 degree. Thanks!
