Hello Nagasawa-san,
If I understand your question correctly, you like to know the CMRR of the final stage of LMH6619-Q1 Figure 12 (Differential Cable Driver).
I've attached a document which should help with this computation assuming a certain resistor…
Other Parts Discussed in Thread: LMH6601 , LMH6559 , BUF602 HI~
I need to design an input 1.2V/1.8V/3.3V, the Buffer 400MHz of bandwidth. Please provide the recommended parts and circuits.
Thanks for your support!!

Vianney,
I have no personal experience with the LMH6601 or LMP7717 as I support the "OPA" branded products. Upon quick look, they look like reasonable possible selections. You may also want to look at OPA356 and OPA365 which resemble these "LM" products…
Other Parts Discussed in Thread: LMP7721 , LMP7711 , LM6211 , LMH6601 , OPA355 My application is a low noise charge amp. Thus, knowing the CM and DM input capacitances is important for predicting the white input referred voltage noise density. Unfortunately…

I have a voltage signal in the range of 10 µV which should be amplified…
Hello Alexey,
Regarding your comments on low power distortion getting worse based on the LM4562 Figure 4 and Figure 25:
These plots at “low x-axis (output voltage)” are mostly a measure of the output RMS noise (not distortion). In this low output power…
