LMK1C1104: Current consumption

?? ??

Part Number: LMK1C1104

What are the conditions for the test circuit in Figure 7-1?

How should I estimate the power supply current consumption when using a 50OHM load via a DC blocking capacitor as the output load? All 4CH TOTAL

Hello,

The test conditions can be seen as below, except in the case of 7-1, the 2pF capacitor is actually 5pF.

The current consumption of this device will be slightly lower than what is shown in Figure 7-1 when used without the 5pF load specified in the test setup in the datasheet.

Thanks

The second question is assuming the following circuit.
Is the current consumption graph the same?

Hello,

The current consumption in the graph will be slightly increased due to the different shunt capacitor value, but not by a significant value. The DC block's contribution to the current consumption is trivial. You can assume that the current consumption graph will be the same.

Thanks,

Michael
