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
INmin
= 0V
– gain at full scale (for example V
IN
=250mV)
3. Monotonicity guaranteed if V
IN
increases or decreases in steps of min. 5mV.
