Absolute Maximum Ratings

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation

of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum

rating conditions for extended periods may affect device reliability.

Electrical Characteristics

(VDD = 4.75V to 5.25V, VOVDD = 2.3V to 5.25V, fSAMPLE = 500kHz or 250kHz, VREF = 4.096V; TA = TMIN to TMAX, unless otherwise

noted. Typical values are at TA = +25NC.) (Note 2)

Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer

board. For detailed information on package thermal considerations, refer to
