TI just discontinued my favorite voltage reference, the LM329. I bought another 250 so I can use them in protos forever, but no more in production designs. :(
Being basically the guts of an LM399 minus the heater and fancy package, they're a good 20 dB quieter than bandgaps, and super cheap while they're still available.
Razza frazza sfmmfmmgn....bastards.
