I am working on the aducm350 eval board and I wanted to know the highest freq I can code in it for the 2 wire bioimpedance sampling.
I am using 2/4 wire config, without the iso capacitors.
I wanted to use this chip for the bioimpedance spectroscopy and hence I wanted to know how high can I go in terms of "frequency" of sampling. If I understand correctly, the highest I can go is the 78kHz? But I tried even higher frequencies and sometimes there was reading out of DFT and sometimes not. If someone could shed some light on this?
so, the datasheet says - 160kSPS, does it mean I can at max do 80KHz for the sampling freq?
It can go up to 80KHz, but I'd say it working perfectly up to 50kHz. If you're using 80KHz, please try to increase your sampling time.
