There are 2 markets for DACs and ADCs.  I'll call them DC and RF, but the RF 
goes down to audio.

In the DC market, the data sheet talks about linearity and usually covers 
temperature stability.

In the RF market, the data sheet has Fourier transform plots when the input 
is a clean sine wave or pair of sine waves.   Think software radios, radar or 
spread spectrum.  The usual one term summary is ENOB: Effective Number of 

In the RF market, nobody cares about temperature drift.

These are my opinions.  I hate spam.
