differential outputs are in same phase and does not producing the required mean

Category: Hardware
Product Number: ADA4930-2

Hi team,

Iam using AD9652 ADC in which input is fed through AD4930-2 op amp. Iam using the reference design given in AD9652 datasheet. But  output of OP Amp is not truly complementary. The output differential pair is  generating with same Phase. 

AD9652 is expecting true complementary input, but the op amp is not producing the required mean level and complementary outputs. 

please look into the issue at fast.

Thanks & Regards,
