ADC CHARACTERISTICS (Cont’d)
Notes:
1. Data based on characterization results over the whole temperature range, not tested in production.
2. For precise conversion results it is recommended to calibrate the amplifier at the following two points:
– offset at V
– gain at full scale (for example V
3. Monotonicity guaranteed if V
4. Please refer to the Application Note AN1830 for details of TE% vs Vin.
5. Refer to the offset variation in temperature below
Amplifier output offset variation
The offset is quite sensitive to temperature varia-
tions. In order to ensure a good reliability in meas-
urements, the offset must be recalibrated periodi-
cally 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:
