2.CHARACTERISTICS AND SPECIFICATIONS

(All Min/Max characteristics and specifications are guaranteed over the Specified Operating Conditions. Typical

performance characteristics and specifications are derived from measurements taken at nominal supply voltage

and T

= 25°C.)

SPECIFIED OPERATING CONDITIONS (AGND = 0 V; all voltages with respect to ground.)

ABSOLUTE MAXIMUM RATINGS (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.
