Hello,
I am looking to PGA281 datasheet.
In there, I cannot understand Figure 38.
If 8Vpp applied to the input, each VOP, VON will show 2Vpp. (I agree)
but, why differential VOUT will be 4Vpp? ( I cannot understand)
VOUT=VOP-VON, so, VOUT should be 2Vpp (3.5V-1.5V= 2V)
(G =1/4, so 8Vpp X 1/4 = 2Vpp)
Can anyone help me understand Figure 38?
Thank you for your help in advance.
Best Regards
HJ Jeong
