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.

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.
