Hello,
My questions are related to the following one, but does the input impedance have dependency on fs? The datasheet says 60kΩ(typ) at fs=48kHz, but is it the same for fs=16kHz or 96kHz?
Best Regards,
Yoshikazu Kawasaki

Hi Kawasaki-san,
The input impedance actually is affected by the sample rate and is nominally 60kOhm at 48kHz. Please see this thread for a typical curve of input impedance vs. sample rate: https://e2e.ti.com/support/audio/f/6/p/963547/3559654#3559654
