According to AD9235 datasheet. There are 2 type of input circuit.
On page 16, Figure 35, AD8138 Positive output go to AD9235 VIN+, negative one go to VIN-.
On the other hand, page 23, Figure 46 shows analog input circuit on AD9235 EVM that AD8138 VO+ go to AD9235 VIN-.
I would like to know, why and which one is the best case for the AD9235 and ADC Driver?
Thank you for your help in advance.
