LTC1407 driver + OP AMP

Hello everyone,

I would like to ask you for my new ADC design: LTC1407

I have a requirement of 500kHz BW with 100dB gain. I would like to have differential input and output.

DS provides an OP amplifier as a suitable driver. However, I need to fullfill a 100dB gain within 500kHz BW.

Thanks in advance for your support.
