Hi at all,
I have a question about the ADS1298R Evaluation Board.
For the measurement of the respiration there is a circuit on the board (see picture 1). And for limitation of the current I_Resp there are two resistors on the board (R96 and R97, both 40.2k), see also Equation in picture 2.
My question is: up to what value can I limit the resistors (R96 and R97) to increase the current through the body? What is the maximum current of the internal current source of the ADS? I found no limitation / value in the datasheet (SBAS459J).
Thanks a lot,
Constantin
