1. CHARACTERISTICS AND SPECIFICATIONS

ABSOLUTE MAXIMUM RATINGS

AC & DC PARAMETRIC SPECIFICATIONS (AGND,DGND = 0 V, all voltages with respect to 0 V)

WARNING: Operating beyond these limits can result in permanent damage to the device. Normal operation is not

guaranteed at these extremes.

RECOMMENDED OPERATING CONDITIONS (AGND,DGND = 0 V, all voltages with respect to 0 V.)

Note:

Operation outside the ranges is not recommended.
