| Nov 20, 2015 at 19:07 | comment | added | JEFENZ0 | Thanks for the great link! If I am understanding correctly the amplifier does a lot, but one way it increase the reading accuracy is by stabilizing more bits. The amplifier does not increase the resolution to below 0.303 mV. On quora (top answer under bold range adjustment header - the link in 2nd comment below) it says using the full range of adc increases precision in temperature reading, does this not apply to increasing the precision of sensor's voltage reading if I amplify from 200 mV to 1.24 mV with the appropriate amp. If I do amplify would my new precision be 0.05 mV with a 12bit adc. | |
