DYNAMIC ELECTRICAL CHARACTERISTICS
Table 4. Dynamic Electrical Characteristics (continued)
All characteristics are for the analog chip only. Please 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 ≤ 125°C unless otherwise noted.
Typical values noted reflect the approximate parameter mean at T_A = 25°C under nominal conditions unless otherwise noted.
