Some time back I had a thread on subject ( http://www.8052.com/forum/rea...5151)using the Silabs C8051F020
MK had suggested an input attenuator circuit to handle +/-10V and convert same to 0-2.5V using resistors. I had missed the original thread on the subject, but you may still find my design idea ("Use Excel To Calculate A-D Level-Shifter Resistor Values") pertinent.

| Good link that.. | 01/01/70 00:00 | |
| Wont work | 01/01/70 00:00 | |
| It should have been +/- 15V | 01/01/70 00:00 | |

| Thanks. | 01/01/70 00:00 | |
| I would eventually omit the input buffers... | 01/01/70 00:00 | |
| Now that is worrying.. | 01/01/70 00:00 | |
| What I meant... | 01/01/70 00:00 | |
| Inputs swapped | 01/01/70 00:00 | |
| Extremely sorry for the goof up. | 01/01/70 00:00 | |
| Some hints... | 01/01/70 00:00 | |
| Just in time... | 01/01/70 00:00 | |
| As long as... | 01/01/70 00:00 | |
| Yes I understand. | 01/01/70 00:00 | |
