ELECTRICAL CHARACTERISTICS
STATIC ELECTRICAL CHARACTERISTICS
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 ≤ VSUP ≤ 16 V, -40 °C ≤ TJ ≤ 125 °C, unless otherwise noted. Typical values
noted reflect the approximate parameter mean at TA = 25 °C under nominal conditions, unless otherwise noted.
