Besides the question above, for my circuit I need to handle both high frequency and low frequency signals. And I am using both DAC7821 and ADS1605. Thus I am wondering what the frequency responses for them look like? In particular, whether the frequency response still has a rather flat frequency response at DC?
Another question is specifically about the positive supply circuit listed as Fig 28 in the datasheet for DAC7821. What bypassing capacitors do you recommend for this circuit (value and number)?
I really appreciate your help and thank you in advance!
