User436186,
First what have you tried to get register mode going? Are you getting bad reads? Can you not change registers? You'll have to describe the problems you are having and what it not working. I would also help to have scope shots if the data…
Other Parts Discussed in Thread: OPA1632 , ADS1281 , TINA-TI Hi,
I'm try to use ADS1281EVM.
And the circuit is shown as following:
The OPA1632 is the preamplifier
My questions are:
1. How is the circuit function of OPA1632? LPF or buffer?…
Other Parts Discussed in Thread: ADS1281 Hello.
I'm encountering issues using ADS1281 converter.
I want to read the converter with a data rate slower than 250sps.
I'm in register mode and continuous mode.
These are my register configurations …
Other Parts Discussed in Thread: ADS1281 Hi
I have a problem with ads1281,it sends random values, sometimes around the value expect (no input signal just input offset).
The phenomenon that described in the attached file occured.
I have take 1000…
Hi Bart,
Welcome to the TI E2E forums, and please forgive the delayed response to your question!
If you're seeing 1000 ppm of non-linearity, then you are only getting about 10-bits of performance out of the 31-bit ADS1281. That tells me there is a…
Other Parts Discussed in Thread: ADS1281 We need to exploit a data acquisition system of 15 channels [DSP(C6748)+ARM(OPAM138)+AD (ADS1281)]
We use DSP to gather the data of AD by way of GPIO, it's normal; When we use ARM and DSP (dual-core communication…
Other Parts Discussed in Thread: ADS1281 Dear Support,
I have the ADS1281 in Unipolar configuration (0 to +5V), Vref=+5V.
Please provide a Code table in FIR Filter configuration for the following voltages, similar to Table-14 on page 24 in the Data…
Other Parts Discussed in Thread: ADS1281 , ADS1282 Looking for a highly accurate ADC. I do not need internal PGA , the logical choice would be ADS1281 , but I do not know why ADS1282 has better INL 0.5 ppm vs 0.6 ppm. I assumed that the ADC is identical…
Hi Gioacchino,
We do have parts that support daisy chain mode, but the ADS1281 is not one of them. However, it does have two modes of operation:
Pin mode
Register mode
Pin mode is less complex to program, but I think it would require more…
Chris san, Thank you for your reply! Compared with comeptetion ADI7172-2(please refer to the following datasheet), the power dissipation is 19mW. http://www.analog.com/media/en/technical-documentation/data-sheets/AD7172-2.pdf Certainly, ADS1281 is good…
