Amplifier output offset variation
The offset is quite sensitive to temperature variations. In order to ensure a good reliability in
measurements, the offset must be recalibrated periodically i.e. during power on or whenever
the device is reset depending on the customer application and during temperature variation.
The table below gives the typical offset variation over temperature:
