I'm not sure which type of adau1701 output I should use (Passive vs Active), what are the advantages of one over the other, not to mention the cost?
When using AD8608 or another operational amplifier...
a) Is there any gain in quality?
b) Are there any changes in the output voltage?
Also, about the OSC pin, should I leave the left float when using Active Oscillator? (4 Pins with vcc ), does this type of oscillator have enough power to be used with four external ADCs, without using a buffer?
Thanks in advance.
