Data Sheet Clarifications
The following typographic corrections and clarifications
are to be noted for the latest version of the device data
sheet (DS41639A):
1. Module: Electrical Specifications
29.9 AC Characteristics
Removed “No missing codes” from AD03
Conditions column, and modified Note 2. Under
very rare circumstances, a single code can be
missed.

* These parameters are characterized but not tested.
† Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not
tested.
Note 1: Total Absolute Error includes integral, differential, offset and gain errors.
2: The A/D conversion result never decreases with an increase in the input voltage.
3: ADC V
REF is from external VREF+ pin, VDD pin, whichever is selected as reference input.
4: When ADC is off, it will not consume any current other than leakage current. The power-down current specification
includes any such leakage from the ADC module.
