About THDB-ADA and other AD/DA Daughter cards

Hello all,

According to the User's Guide of THDB-ADA (AD/DA converter), DC signals and low-frequency AC signals are not supported for AD or DA conversion operations. Since I need an AD/DA daughter card covering the frequency spectrum of (5 Hz - 100 kHz), I wonder what is the minimum supported frequency of THDB-ADA daughter board?

In addition, after some research, I found another AD/DA card: P0035 - [DCC] AD/DA Data Conversion Card and I couldn't see any restriction on the type or the frequency of the signal (AC or DC) in its user's manual. Do you guys know this daughter board support DC signals?

Thanks,
