Hi Chen,
Welcome to the TI E2E Forums!
The group delay is calculated from the digital filter's response. However, in practice it is difficult to verify this timing because your input signal step must occur exactly at the same time when the ADC begins…
Other Parts Discussed in Thread: ADS1281 What is the current pull on the AIN+ and AIN - input lines when nominal voltage is applied (voltage that does not exceed maximum limit and turn ON the ESD protection diodes)?
Other Parts Discussed in Thread: ADS1281 , OPA1632 Hi,
ADS1281 has one differential analog input channel.
But my sensor is 3 pins. (Vin,Vout,GND)
So, the ground of sensor and ADC are the same.
Is the connection in the following figure right? …
The datesheet shows that "Note that a delay of 24 fCLK cycles is required between each byte transaction."in page 31.We want to know the timming of the delay of 24 fCLK cycles.
Whenever the command of WREG or RREG is sent ,the DRDY can not output anything…
Other Parts Discussed in Thread: ADS1281 , OPA735 , OPA227 , OPA313 , THS4531 , TINA-TI Hi,
I want to design a 8-channels recorder.
I use eight ADS1281 ADCs for synchronized.
The Vref design is from the datasheet of REF50xx which is shown in the…
Other Parts Discussed in Thread: ADS1281 Hi,
I'm using the ADS1281 as a data converter for an electrometer application. The converter is working fine. What I'm looking for is a suggested layout for best noise performance.
If anyone has any input…

Dear Sir or Madam,
We are developing a set of data acquisition system with ADS1281. Software and hardware are ready in the test phase now, but some problems are found during the test, so we need some technical…
Other Parts Discussed in Thread: ADS1281 HI,
I use ads1281 for reading 4 different input.
It is configure like that :
Pulse sync mode,4000SPS,Linear phase and Sinc + LPF filtre block
I use the read by command I turn the first channel on and then…
