No difference; the analog signal is inverted, that's all. There's no audible difference.Is there any practical difference between connecting the analog outputs as suggested in this thread (LEFT -> INL+, RIGHT -> INR+, GBUF -> INL-, GBUF -> INR-) and inverting the signal as the USB Recorder schematic shows?
The most important thing is that the RC filter is there. 1K/4n7 and 100/47n give the same RC value, so as per the cutoff frequency, that would be the same. Our chips can drive the 100 ohm load, so that's not a problem. So yes, I think both can be used. There may be some differences, but without doing any measurements, I cannot be sure.And for the low pass filter, any benefit to the 1K/4n7 in the schematic versus 100/47n as suggested in TI's datasheet?
Thanks a lot!Appreciate all the great info you've provided in these forums. Thanks!
