Max/Min drive current and power of ADRF6510

Dear Sir/Madam,

 

As for your VGA ADRF6510, I have a question.
What is the output drive current min and max? Also the electrical power value this can drive.
I would like to know what is the min/max drive ability.

 

"Differential output Impedance" is showed as typ. 20 ohm, and "Max. output swing" is showed as 2Vp-p  on your datahseet.

So how should I think this?


In the case of 20 ohm fixed,,,,,
If the output is 1V DC, the current is 1/20 A.
So the power is 1/20 W.
If the output is 2Vp-p sinwave, the current is 0.7/20 A.
So the power is (0.7x0.7)/20 W.

 

If the above is correct, then how should I the dispersion min-max of "Differential output Impedance"? Maybe you cannot guarantee this due to that it is not put on your datasheet only typ value 20 ohm.


Thanks Kaos
