when I turn on the digital gain , the waveform disorders.
when i turn off the digital gain , it works perfectly.
what can i do to solve this problem?

Hi,
you haven't posted any waveform plots that i can look at so i can't really say, but when you turned on digital gain did you also reduce your signal amplitude by the same anount so as to not exceed the full scale range?

Hello ,
My normal waveform is like this:(decimation filter is bypassed , digital gain disabled, wave amplitude is out of range.)
reg=0x0, value=0x2
reg=0x4, value=0x80
reg=0x4, value=0x0
reg=0xf3, value=0x8
reg=0xea, value=0x80
reg=0x44, value=0x7
reg=0xfe, value=0x5
reg=0x2c, value=0x17
reg=0x32, value=0x2f
reg=0x2d, value=0x3b
reg=0x33, value=0x3b
reg=0x42, value=0x0
reg=0x3d, value=0x20
reg=0x25, value=0x0
reg=0x2b, value=0x0
reg=0x31, value=0x0
reg=0x37, value=0x0
reg=0x45, value=0x1
reg=0xf1, value=0x3
reg=0xfa, value=0x2
reg=0xba, value=0x8
reg=0xe0, value=0x60
reg=0xee, value=0x80
reg=0xf7, value=0x81
When i enable the digital gain 0x42, set bit3 . My disordered waveform is like this: (decimation filter is bypassed , digital gain enabled, wave amplitude is out of range.)
And when i enable the decimation filter (set 0x44=5), the waveform came like this:
