What the heck do certain letters mean in an OpAmp suffix?

[Svart]

like TI lists the tl071 as

tl071cn
tl071acn
tl071acp
tl071ID

does anyone know what A, C, P, I, D mean?

I must be blind as a bat or just dumb because I can't seem to find it anywhere on their site...

Roll down to the second page, there is a chart in the datasheet.

Very simple you must look at the vendors datasheet.
Quick answer usually Temp specs like industrial or commerical
temp ranges. On op amps the offset voltage may be tighter on certian models. Look at the logo on the chip. Figure out the vendor. Look at the data sheet. Skim it again because it is hidden in there.
