I would like to know what would be the maximum recommended resistances to place between an FDA and AD7960 inputs (R3 and R6 on the figure below). I would like to reduce the capacitor value to reduce power consumption of the LTC6363 and increase the resistances accordingly to keep cutoff frequency. I am thinking of 200R or 300R instead of 100R. The input signal is a amplitude modulated sine wave, 125kHz.
Thank you in advance for your inputs.
