Hi,

Technically, it is possible to use DC-coupled input signal. What is this application for?

Thanks,

My problem is not answered, I just never noticed the reply. The application involves reading the amplified output of a photodiode in which the DC offset must be retained.

Hi,

DC-coupled connection to ADC should not impact on DC offset. Should you compensate DC offset or utilize that information for your applications?

Thanks,
