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 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 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!
Part Number: ADS1248 Hi,
Good Day.
I'm looking at the datasheet for the ADS1248 and it says it has 50 and 60 Hz filtering. Is that at all sample rates?
The table on page 30 has dashes for sample rates 40SPS and higher.
We use the ADS1248 on our board…
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 The pseudo code example in section 10.1.7 puts the SYNC outside of the loop. To paraphrase slightly (and omitting the CS commands):
Send SDATAC command (16h) to prevent the new data from interrupting data or register transaction…
Hi huichun xing,
The topside markings on the "bad" ADS1248 indicate that your device was not manufactured by TI. Therefore, we cannot provide any further support on these products. Instead, please communicate with whomever sold these devices…
