So My output peak to peak Swing is approximately :- 1.2V .
I need a gain:- 1 ( used as a buffer)
Input Common Mode Voltage:- 0.65V
My Differential Peak-to-Peak Swing is- 1.3V
But I couldn't derive any conclusion out of this as they are given under specific test condition which are NOT coming under my test conditions.
I carefully went through AD8129-8130 data sheet. I am going to use as a differential -to single ended converter buffer with high input impedance which is going to drive Spectrum analyser i.e. 50 Ohm load.
Signal Band Width ( 3dB) Needed :- 0-3 MHz (only)My Output Load is :- >= 150 Ohm ( 50 Ohm of Spectrum Analyzer + 100 Ohm is put in series with the buffer output)
Linearity is VERY Important for me.
So whether AD8130 will work with 150 Ohm load with the same linearity performance as in the case of 1Kohm load. ?
