3. CHARACTERISTIC AND SPECIFICATION TABLES
RECOMMENDED OPERATING CONDITIONS
GND = AGND = 0 V, all voltages with respect to ground.
ABSOLUTE MAXIMUM RATINGS
GND = AGND = 0 V; all voltages with respect to ground.
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.
Due to the existence of parasitic body diodes between VCP and VA, current flows from VCP to VA when-
ever the VA power supply is lower than VCP. This causes a “back-powering” effect on the VA power
supply rails internal to the part. Hence VA should be maintained at an equal or greater voltage than VCP
at all times. While “back-powering” does not have any adverse effects on device operation with respect
to performance and reliability, it does lead to extra power consumption and therefore should be avoided.
2.
Any pin except supplies. Transient currents of up to ±100 mA on the analog input pins will not cause
SCR latch-up.
3.
The maximum over/under voltage is limited by the input current.
