STATIC ELECTRICAL CHARACTERISTICS
This paragraph is boilerplate - you may add to it but, can not change wording. You may change numeric values
STATIC ELECTRICAL CHARACTERISTICS (continued)
All characteristics are for the analog chip only. Refer to the 68HC908EY16 datasheet for characteristics of the microcontroller
chip. Characteristics noted under conditions 9.0 V ≤ V_SUP ≤ 16 V, -40°C ≤ T_J ≤ 135°C unless otherwise noted. Typical values
noted reflect the approximate parameter mean at T_A = 25°C under nominal conditions unless otherwise noted.
