Notes
22.
This parameter is guaranteed only if correct trimming was applied
23.
The current values are optimized to read a NTC temperature sensor, e.g. EPCOS type B57861 (R25 = 3000
Ω, R/T characteristic 8016)
24.
This parameter is guaranteed by process monitoring but is not production tested.
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 9.0V ≤ VSUP ≤ 16V, -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.
