Hi all, I'm using adau1701 for an active dual channel amplifier to be used in 2-ways loudspeakers.
The dsp is used to drive differentially each input channel of the class d amplifier using an active filter similar to the one described in the datasheet. The measured a-weighted differential noise (dac0 - dac1) is around 100uV rms.
The Fs I'm currently using is 48 KHz. Is there any advantage in increasing the sampling frequency? My idea is that in theory noise shaping would be better.
If yes is there a comparison of Fs vs. output noise vs. current consumption?
