12.4 Temperature Sensor Accuracy and Conversion Characteristics
Notes: 1. Typical values characterized at V
CC
= 3.3V, T
A
= +25°C unless otherwise noted.
2. Sensor accuracy characterized to this range but not tested or guaranteed.
12.5 AC Characteristics
Note: 1. Minimum clock frequency must be at least 1kHz to avoid activating the SMBus Timeout feature.
