9.2.1 Block description
The sensor signal conditioner amplifies and filters the sensor output signal, before converting it to a digital
format.
These are its main features:
Voltage regulator
This block provides the signal conditioner chain and the external sensors with a programmable, stable
voltage for a wide range of sourced currents.
Internal temperature sensor
This block gives a temperature-dependent voltage. As all other sensors, it must be calibrated to give accurate
data.
