4 CHARACTERISTICS AND SPECIFICATIONS
(All Min/Max characteristics and specifications are guaranteed over the Specified Operating Conditions. Typical per-
formance characteristics and specifications are derived from measurements taken at nominal supply voltages and
T_A = 25° C.)

WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation is
not guaranteed at these extremes.
Notes: 1. Analog input/output performance will slightly degrade at VA = 3.3 V.
2. The ADC_SDOUT may not meet timing requirements in Double-Speed Mode.
3. Any pin except supplies. Transient currents of up to ±100 mA on the analog input pins will not cause SCR
latch-up.
4. The maximum over/under voltage is limited by the input current.
