ADC12DJ3200: Need an appropriate single ended to differential driver for this ADC

Part Number: ADC12DJ3200
Other Parts Discussed in Thread: LMH3401, LMH5401, LMH6401

Hi,

Can anyone suggest a single-ended to differential ADC driver for the ADC12DJ3200 ADC. My input is single ended and at zero IF, so I cannot just use a balun. Any help would be appreciated.

Regards,

Sai.

Hi Sai
What is the maximum frequency of your input signal?

Hello Sai
Depending on your gain requirements I would recommend one of the following devices.
LMH3401 - fixed gain fully differential amplifier
LMH5401 - resistor configurable gain fully differential amplifier
LMH6401 - digitally adjustable fully differential amplifier (this can be used in combination with one of the other devices to give best SE-Diff performance with configurable gain)
The information in this reference design may be of interest given your application:
