Most sensors needs some signal conditioner electronics before digitize the signal. Few examples are:
- Piezoelectric force sensors
- Geophone
- Photodiode
- Thermocouple
The signal conditioning electronics can have different functions:
- Amplification
- Isolation
- Filtering
- Excitation
- Linearization
Depending on the electrical quantity that is meaningful for the measurement, different types of amplifiers are used:
- Current to Voltage ([Transimpedance Amplifiers]({{< relref "transimpedance_amplifiers.md" >}}))
- Charge to Voltage ([Charge Amplifiers]({{< relref "charge_amplifiers.md" >}}))
- Voltage to Voltage ([Voltage Amplifier]({{< relref "voltage_amplifier.md" >}}))
