Hi, All,
I am using ads131e08, but I have 2 problem about offset calibration and filter setting. Wish your reply, thanks.
1. when I set data rate to 1Ksps, Mux[2:0]=001(selftest), after I run 1A command(OFFSETCAL), offset of data in each channels is always high. for example CH1-CH8 is 249, 66, 227, 55, 68, 115, 129, -85 in one test.
So whether my configuration sequence is wrong or other reason? 1A command is running after all CHnset register is set.
2.when I set data rate to 1Ksps, Mux[2:0]=000(VIN,VIP of input is connected), the offset of 8-ch data is high as same as before, for example CH1-CH8 is 151, 133, 165, 17, 106, 110, 169, -34 in one test.
I want to know why digital filter has no affect on this configuration. Thanks.
Best regards.
Guan
