Hi, Two suggestions, First the Op-Amp you're looking for will be called rail-to-rail. They allow you to get full voltage swing with a single supply. Second, you might move this to the [EE] tag, as it realy isn't PIC specific. Good Luck -Denny ----- Original Message ----- From: "Mohit Mahajan" To: Sent: Wednesday, October 08, 2003 2:28 AM Subject: [PIC]: Signal conditioning question > Hi, > > Using an LM335 for 0*C to 100*C range in a PIC, I get the output range > from the LM335 as 2.73V to 3.73V.
