LMH1980: Typical power consumption with input signal

Part Number: LMH1980

Hi.

The LMH1980 datasheet states the typical and maximum current consumption when there is no input signal.

How much can I expect this to increase when applying an input signal?

Hi there,

Sorry to keep you waiting, unfortunately, we are not able to find an analog video source to verify the current consumption.

We have tried using a single frequency signal (no modulation, pure sine wave signal), the highest current the eval board consumes is 12mA @5V supply. Without input signal, current is just 9mA.

Hi Noel.

Thank you for really trying to help out. I can't say that this issue was solved but you can close it.

I will measure the consumption myself later on.
