Hi Kuo,
For the AD817 (+/-18V supplies, 350 V/us slew rate, good video performance, 50MHz, unlimited cap load, 7.5mA supply current), the closest device is the LM7171 (which is not really rated for "unlimited cap load" but might otherwise fit).
However…
Hi Daram and Samir,
The problem with the LMH6629 TINA-TI simulation file was that the current source was set to off:
Here is the AC response with the current source state changed / corrected (set to "None" instead):
Here is the new simulation…
Hi Pranav,
In the register file you had attached, the 1st line you have shown:
"SPI_SENDDATA(0x1F 02 ); // Page 0"
However, I believe this should have been what is shown below instead if your intent was to set the Page Register to Page 0:
"SPI_SENDDATA…
Hello Jarrett,
The Figure 8 in the LMH6628 and the LMH6628QML datasheets (Frequency Response vs. Capacitive Load) is probably not the plot you had intended to point to because it does not involve your question about "the amplifier's ability to reach…
Hello,
When you switched the LMH6628 to single supply, did you make sure you observed the input voltage range as well? It would be best if you attach your schematic to discuss.

Hi Salil, As you've also noted, the LM7171 slew rate is a strong function of input differential voltage as shown in Figure 23 (Slew Rate vs. Input Voltage) where it ranges from 600 V/us (x-axis = 1Vpp), to just over 3,000 V/us (x-axis = 10Vpp). With closed…
Hi Spanika,
I agree with the way you've computed noise power density (dBm/Hz) from the known value of noise voltage density (nV/RtHz).
So, the 9.12uV/RtHz translates to -87.8dBm/Hz, referenced to 50ohm, according to your formula.
Here is some additional…
Hello,
To add Loren's comments:
The 100nF cap and the 10 kohm resistors are to make sure the input / output swing is well centered around Vcc/2, if you can deal with AC coupling the signal. Assuming you use the LMH6559 with 5V single supply (Vcc and…
