The inversion would be handled by the input circuit. The A/D would not see it. Some A/D data sheets I have in the past say the A/D read the input as both polarities to get the sign and set the conversion direction.
I did say the offset is more common. |

| can you please be specific | 01/01/70 00:00 | |
| negative readings? | 01/01/70 00:00 | |

| Looks like it cannot be done. | 01/01/70 00:00 | |
| you can | 01/01/70 00:00 | |
| Exlain | 01/01/70 00:00 | |
| OK, like this | 01/01/70 00:00 | |
| Thanks | 01/01/70 00:00 | |
or you can use opamp as non inverting summing amp. | 01/01/70 00:00 |
