Thank you Sima,
Can you please review the attached circuit? Output of these 2 channels feed to the ADC 2 channel inputs.
We have a requirement of LMH6554's loop filter to satisfy
Pass band frequency: 15MHz - 750MHz Sharp rejections at 750MHz and…
Part Number: LMH6554 Tool/software: Hi
we are using P/N: LMH6554LEE in our design, please find the below image for reference and can you share the maximum input supply current for +2.5V and -2.5V.
Thanks in advance.

Part Number: LMH6554 Tool/software: Hi,
I have a question regarding the power supply requirement for the LMH6554 full difference amplifier.
I want to use this amplifier as a current sensor amplifier along with a shunt resistor. The current is expected…
Hello Gozkul,
You could try forcing the common-mode voltage of the ADC to be 2.5V from the same supply as the VCM pin of the LMH6654.
The problem may be the common-mode voltage of the ADC is different from the 2.5V supplied to the LMH6554, which results…
Part Number: TINA-TI Other Parts Discussed in Thread: LMH6554 Tool/software: Hi, I am trying to simulate the behavior of LMH6554 while driving a switched capacitor load (red circled). You can see the switches parameters. The nets Vop and Vom saturate although…
Hello Dan,
This could be impacted by resistor choices. I’ll have some time tomorrow afternoon to ask around.
It may also be splitting hairs, that’s part of the fun of analog.
Best,

Hello Felix,
I was able to discuss with my colleagues; I do think the overdrive recovery and optical TIA application needs are met by our OPA85X family of parts. If you do still require overdrive recovery data on these LMH parts, do know that with a high…
Part Number: LMH6554 I'm following the guidelines from the LMH6554 datasheet and the evaluation board sheet for my design. I realized there are a couple of discrepancies in the application information for single-ended input to differential output con…
