3. Guaranteed by design and/or characterization.
4. Limited by output swing and internal gain.
5. Output low voltage level is limited by the internal level shift circuitry.

6. The normalized gain is guaranteed by design and characterization. The max normalized gain of +0.8 dB is the result of smooth peaking
(preemphasis, see figure 2) taking into account the increase of the losses at the highest frequencies into connectors and cable at the output.
For frequencies lower than 2 MHz the max normalized gain is 0.4 dB.
