Other Parts Discussed in Thread: PCM1808
Hi,
I'm looking at PCM1808 and the internal antialiasing filter.
According to the datasheet the cutoff frequency for the LPF is 1.3MHz and the delta-sigma modulator is 64 times FS.
Does that mean that an external LPF is needed if FS is less than approx. 41kHz?
I will be using it with FS at 16kHz
Best regards
Gert Jensen
