those of you who use the "ad7195"?
when is it use in NO ACX MODE, channel selected AIN1(+) AIN2(-), BIPOLAR SELECTED, INPUT RANGE +/-39,06 Mv,  continuos read, at input=0mV the value is 0x000000 or 0x7fffff?

My firmware read from  about 0x000000 (at 0mV) to up (example at +10mV ,read 0x500000 ), while with negative values the value read is always 0x000000.

The same firmware with ad7730 is correct.

who can help me?
