    I am new to forum and need asistance. I want to make the OP amplifier for measuring temperature from-20C to +200 C with ADC Vout 0-5V . Please if anyone has a scheme that we send. In my project, I already have a Vref = 5V (REF02), Vcc = 5V (7805) Vcc1 = 10V (78L10). Op amps than I have available LTC271CP, AD620, AD621, LM324, LM358. The microcontroller ATMEGA16-16MHz. Extenal ADC MCP3204.

    Please post your circuit. What temperature sensor are you using?
