Hi, Team
our customer use ADC5140 in their pro audio speaker, and they use DC-coupled for input signal.
and they prefer to adjust the input impedance to improve the system performance. they find 2.5kΩ should be a good input impedance for their system.
But from the ADC5140 datasheet, it shows "The input impedance value of 2.5 kΩ is not supported for the DC-coupled input."
Could u help to share more detail about that? why our device can not support 2.5 kΩ impedance while using DC-coupled?
Thanks.
