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
(VPVDD = 18V, CIN = 1FF, VSHDN = 5V, LIM_TH = VS, TEMPLOCK = unconnected; G1 = GND, G2 = open (gain = 20.1dB), CREL
= 1FF, C1 = C2 = 1FF, RL = J, AC measurement bandwidth 20Hz to 20kHz, differential input signal, TA = TMIN to TMAX, unless
otherwise noted. Typical values are at TA = +25NC.) (Notes 2, 3)
ABSOLUTE MAXIMUM RATINGS
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 www.maxim-ic.com/thermal-tutorial.
