Notes: 1. ZAL refers to the analog output pin loading and CDL refers to the digital output pin loading.
2. Parameter definitions are given in the Parameter and Term Definitions section.
3. Path refers to the signal path used to generate this data. These paths are defined in the Parameter and
Term Definition section.
4. Typical measured with ZAL = 47 kΩ/680 pF load.
5. This specification is guaranteed by silicon characterization, it is not production tested.
