Hi,

Can Anyone help to address below query.

1. How the input signal BW and Filter details ( LPF and HPF cut-off details)

2. Channel sampling and related ODR for each channel

Please see the ADS1293 datasheet, section "8.4 Device Functional Modes" (starting page 33) for detail information.

Hello Mirshab,

I have gone through the data sheet, but require more details such as:

1.How the input signal BW and Filter details ( LPF and HPF cut-off details)

2. Channel sampling and related ODR for each channel

Section 8.4 mentions bandwidth, but what is the low-frequency and High-frequency cut offs? That is not provided, Again, how the sampling frequency and ODR are related w.r.t to BW is not clear.

Thks&Rgds,

Umamahesh

The digital filters do not provide a band-pass behavior, only a low-pass. The bandwidths provided in the table are the simulated cutoff frequencies of the decimation filters. The bandwidth is approximately equal to (Output Data Rate)/(5), but the numbers in the datasheet come from simulation.
