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
(VCC = 3.3V Q10%, TA = -40NC to +85NC, unless otherwise noted. Typical values are at VCC = 3.3V, TA = +25NC, unless otherwise
noted.) (Note 3)
ABSOLUTE MAXIMUM RATINGS
Note 1: Signals on SEL, SELB, AIN_, BIN _, AOUTA_, AOUTB_, BOUTA_, and BOUTB_ exceeding VCC or GND are clamped by
internal diodes. Limit forward-diode current to maximum current rating.
PACKAGE THERMAL CHARACTERISTICS (Note 2)
Note 2: 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 www.maxim-ic.com/thermal-tutorial.
