Its 8 ppm/°C temperature coefficient and 3 µVp-p noise (0.1 Hz to 10 Hz) make it a fit for precision data-acquisition chains — SAR ADCs, bridge-sensor excitation, or the reference input on a DAC — where the reference drift directly sets the system accuracy floor.
The REF5025AID (tube) and REF5025AIDR are electrically identical — same 2.5 V output, ±0.1% tolerance, 8 ppm/°C drift, and 8-SOIC package. The only difference is the reel or tube packing, which matters for pick-and-place volume.
