Exo Active Member Jul 24, 2005 #1 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

J Jay.slovak Active Member Jul 24, 2005 #3 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...).

Exo Active Member Jul 24, 2005 #4 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
