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.
To get a gain of 100dB with 500kHz of bandwidth you will need a minimum of 2 op amps. I suggest you look at the ADA4940-2.
Hi Ghoover, thanks for your reply. I am using an instrumentation amplifier at the input and later I plan to use a chain of OP. I would need to confirm how this would affect my driver input (I will use the one it asks DS)
Can you provide a schematic of what you plan to use?
