I realized on my drive home that I forgot this one:

package AD_Converters is
   type AD_Converter (<>) is limited private;
   procedure Op (ADC : AD_Converter);

   Noise : constant AD_Converter;
private
   type Rep_Type is limited record ... end record;

   type AD_Converter is access all Rep_Type;
   for AD_Converter'Storage_Size use 0;

   Noise_Object : aliased Rep_Type;
   Noise : constant AD_Converter := Noise_Object'Access;
end AD_Converters;
