11.6 Timing and Electrical Characteristics
MC68HC705P9 — Rev. 4.0
MOTOROLA
1. V
2. ADC accuracy may decrease proportionately as V
3. t
4. Source impedances more than 10 k adversely affect internal RC charging time during input sam-
5. t
6. External system error caused by input leakage approximately equals R source times input current.
