Other Parts Discussed in Thread: INA128 , ADS1251 Hello,
For my thermocouple acquisition, I use an INA128 (gain=1000) and ADS1251 for A/D conversion. I want to add a switch between thermocouple and INA128, to wire alternatively the ground or the signal…
Hi Friedrich,
Welcome to the TI E2E Forums; those are excellent questions!
Yes, offset drift (and any specification given as parts per million) is referenced to the ADCs full-scale range (therefore, 1 ppm = 2 * Vref / 1,000,000).
Offset drift is usually…
Hello Samir,
thanks for your reply ! Your suggestion (Rc=175 Ohms) improves the response, there are no perturbations anymore when I connect the INA128 to the OPA698. It works well. Unfortunately, when I connect the OPA698 to my ADC (ADS1251), the systems…
Hi t90ad,
Welcome to the TI E2E forums!
I can help answer any specific ADS1252 related questions you may have... Interfacing to the ADS1252 should be straightforward because you need only to clock out data following a /DRDY interrupt.
You might find this…
Other Parts Discussed in Thread: OPA4350 , LM741 , ADS1251 Hi everybody !!! :)
I have a problem with rebuilding the signal in the computer, the Aliasing, so I need to find where is wrong, please just tell, if I've got a sample rate of 2400 KSP/S, then, …
Other Parts Discussed in Thread: ADS1251 , MSP430F449 , ADS1252 , INA125 , INA122 , REF5030 I'm using an ADS1252 with a strain gage and am interfacing with an arduino. The ADS is not working as expected and I want to ensure that I've got it wired correctly…
Hi Jose,
Do you have a specific question about reading and writing to the control registers in the ADS1255? Pages 34-37 in the datasheet explain the SPI commands.
If you want to use a different part without registers, look at the ADS1251, ADS1252, ADS1253…
Hi Dennis!
Welcome to the e2e forum! We'll take a look over your code and schematic for the ADS1255. In the meantime, here is an app note on setting up the ADS1251 and ADS1252 with one of our MSP430 devices that might help you out. The ADS1251 and…
Other Parts Discussed in Thread: ADS1251 , ADS1252 Hello all,
The datasheet lists ADS1252/ADS1251 as having only one CLK pin.
Most ADCs have two pins (usually called XTAL1 and XTAL2, in my experience)...
So how would I connect, let's say, a 4MHz crystal…
Hi Gamin,
Thanks for your question!
Given your requirements above, and more specifically your most important consideration, I would have recommended the ADS1251. So, I agree with you that the ADS1251 fits the bill well. As far as programming the device…
