I designed a circuit,which is for measuring temperature. I used 12bit a/d converter in TI's msp430 mcu,the result of a/d always jump up and down. In 16 samples,the max value is greater than min value about 8 or 10. Why? And how can i avoid this? The op-amp is op291. I can send you the SCH and PCB, if needed. firstname.lastname@example.org Thanks alot.
