I am designing in the AD8338 in a new design, and I have some questions about driving it single-ended and AC-coupled in an audio application. Please refer to the attached schematic excerpt...
Do the AC-coupling capacitors need to be balanced when using this device single-ended (i.e. - can I use 220uF on the INPD input and .1uF across VREF/INMD)?
Can I eliminate the 50-ohm resistor on the INMD input (R6 in this example) and just connect the cap from INMD to VREF?
Thanks in advance.
