As shown in the circuit above, I am using ADA4938-2 as an ADC driver for AD9269.
The single-ended input signal (V_IN) ranges from 0 to 1 MHz. For RC network value selections, page 21 of AD9269's datasheet recommends 33 Ω series resistors and 22 pF differential capacitors for signals ranging from 0 to 70 MHz. However, it states that this is only a starting guide, and I should choose based on my input signal.
Based on my understanding, 10 Ω series resistors and 1 nF differential capacitor (-3dB BW = 15.91549 MHz), should suffice for my use case right? (-3dB BW = 15.91549 MHz)
I wonder how the series resistors' value would affect ADA4938-2's current consumption. Will the current consumption be lower if I use series resistors with higher values (and adjust the differential capacitor accordingly)?
Thank you.
