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 VINmin = 0V

– gain at full scale (for example VIN=250mV)

3. Monotonicity guaranteed if VIN increases or decreases in steps of min. 5mV.
