Voltage reference ic for A/D

[Exo]

Hello,

Does anyone know a good, commonly used voltage reference IC for use as positive reference for a pic A/D...

Voltage should be 2.5 V.

As simple as possible, a 3 pin ,in-out-gnd ic is preferred..

TY

MicroChips MCP1525 2.5v voltage reference
in a 3 pin TO-92 package

TL431 is a good one too, it's 3pin, 2.5V or Adjustable 1.25 to 37V. I think it's cheaper and more available then Microchips part (but it can be sampled...).

Thanks to both of you.

I think i'll go the MCP1525. I can get them over here and it's also available in SOT23 smd package .. i dont have much room to spare
