#130485 - ADuC Responding to: ???'s previous message |
I use the aduc834 it has a 24bit and a 16bit adc. I 'only' get 14 bits from the 24bit adc. Is the difference between the two sensors simply and offset or gain? If it is offset, the two signals will track each other and the difference will remain the same whereas gain will have the two signals converge/diverge over the full range. Both these can be resolved in software. The aduc834's have eeprom that can be used to store the calibration values which saves another external ic. |
