As described in the subject I'm using the ADS62P42 in CMOS MUX Mode and I'm receiving the result for Input B and I'm getting garbage near noise for input A. If I switch I and Q I can really see that the problem is comming from input A. Is there some SPI register values that can be miss-set like a different gain for input A ? I have to mention that all 3 parallel control pins are at GND to have serial (SPI) config only and that I put in register 14 the power down mode at 111 (MUX mode)
Here are the content of my spi registers
register 00 0x02 //at the beginning to reset everything
register 10 0x00
register 11 0x0c
register 12 0x00
register 13 0x10
register 14 0x80
register 16 0x00
register 17 0x0c
register 18 0x00
register 19 0x00
register 1A 0x80
register 1B 0x03
register 1D 0x00
