We are looking to introduce the LMH6553 fully differential amplifier with output limit clamping to our design, but we are having problems understanding the datasheet regarding the noise data.
The datasheet shows two graphs, in figures 43 and 44, where the vertical axis is in dB, but it does not state what this is in respect to.
The figures also don’t agree with each other, even though they seem to show exactly the same test conditions.
Please could you clarify data around the noise figures for us?
