Most sensors needs some signal conditioner electronics before digitize the signal.
Few examples are:

-   Piezoelectric force sensors
-   Geophone
-   Thermocouple, ...

The signal conditioning electronics can have different functions:

-   Amplification
-   Isolation
-   Filtering
-   Excitation
-   Linearization
