Part Number: ADS1281 Can 1281 be powered by a single supply, such as AVDD=5V, AVSS=GND, VREFP=4.096V, VREFN=GND. If possible, is the analog input range still from VREF/2 to - VREF/2? At this time, can it be from positive 2.048V to negative 2.048V?

Hi Team, seeking your assistance.
I want to ask a question about ADS1281's digital filter feature. I've read the datasheet, where I learned from the 'Electrical characteristics' that the -3dB cut-off frequency of the FIR filter…
Part Number: ADS1281 Hi
I am using ADS1281 ADC for my project. For analog inputs I am using differential signal with a DC offset of 1.25V. My reference voltage values are 2.5V and -2.5V. My expectation is getting the numeric value of the difference of…
Part Number: ADS1281 Hello,
How to decide the Input sample rate，Decimation factor， Decimation offset， Estimated delay of the SESSION 1-4 stage FIR filter? I didn't find the detail description of the ADS1281 datasheet。
Best regards

I've watched videos in 'TI precision labs - ADCs' and benefited from it. But I'm still confused about some parameters of practical ADCs and their usage for my…
Part Number: ADS1281 Hi,
Catalog Number - ADS1281PWR.
I can't use SPI communication lines so I connect the M0 and M1 Inputs ports to the FPGA. Within the FPGA I compute the Y[n] function and get results in the range of -24 to +25.
When I only used…
