DIGITAL CHARACTERISTICS
(T
A
= 25° C; VA, VD = 4.75V - 5.25V)
ABSOLUTE MAXIMUM RATINGS
(AGND, DGND = 0 V, all voltages with respect to 0 V.)
RECOMMENDED OPERATING CONDITIONS
(AGND, DGND = 0 V, all voltages with respect to 0 V.)
Notes: 8. Any pin except supplies. Transient currents of up to 100 mA on the analog input pins will not cause SCR
latch-up.
9. The maximum over or under voltage is limited by the input current.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
