Take a look at the 74HC4051/74HC4052/74HC4053 analog multiplexers. It may be what you need. Some advantages of these parts are: low price (0.5$ or less, way cheaper than the MAX350), easy interface (one to three pins, depending on the part used), and availability. ....and very high crosstalk etc etc. There is a reason why you must use decent Mux chips.

| what type of analog signal you are talking about? | 01/01/70 00:00 | |
| I would not, but | 01/01/70 00:00 | |

| BUT | 01/01/70 00:00 | |
| Then again | 01/01/70 00:00 | |
| Negative readings | 01/01/70 00:00 | |
| Datasheet! | 01/01/70 00:00 | |
| can you please be specific | 01/01/70 00:00 | |
| negative readings? | 01/01/70 00:00 | |
| Not allowed? | 01/01/70 00:00 | |
| Negative ADC readings - again | 01/01/70 00:00 | |
| Like this | 01/01/70 00:00 | |
| I do not understand | 01/01/70 00:00 | |

| Another BANG! | 01/01/70 00:00 | |
| I assumed | 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 |
