Thanks, but unfortunately I have no reference with the 50 Hz and the averaging will increase the sample time. I have around 100mV of noise pk to pk and 1 degree corresponds to about 50mV . If I modify the pcb so that I use the differential inputs of the ADC, will I still be able to solve the...
Hi,
I'm using the 12 bit ADC on a Silabs C8051F040 processor (pdf on Silabs site) to measure temperatures via a series of thermistors.
The thermistors are 10K at 25C ntc and they are each wired in series with a resistor of 10K and fed from a fixed reference source of 2.4V . (at 25C pd will be...
