Table 3. 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
≤ 125°C unless otherwise noted. Typical values
noted reflect the approximate parameter mean at T
A
= 25°C under nominal conditions unless otherwise noted.
