This is one of several that come up when I do a search at Mouser:


That’s the link, to the full reel. At one piece they are $5.89 each. 

Temperature spec is +/- 2.5 ppm over -30 to +75C.  Runs off of 3.3V at low current.

Many of these parts are compensated to be pretty flat past room temperature. If it was a straight line (which it most certainly is not) you might get 0.25 ppm over 10C. If you are after a normal room environment, it’ll swing 2 to 4C.
