there is no need to amplify ......... just set the reference voltage of the ADC0804 2.5v
then your step size of ADC is around 10mv and you will get easily the accurate temperature with increasing hardware...
after reading the byte from the ADC just write the routine Binary to BCD u will get the temperature value
