Table 91.
1. Data based on characterization results over the whole temperature range, not tested in production.
2. Please refer to the Application Note AN1830 for details of TE% vs Vin.
3. Refer to the offset variation in temperature below
4. Monotonicity guaranteed if V
5. For precise conversion results it is recommended to calibrate the amplifier at the following two points:
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:
