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 http://www.maxim-ic.com/thermal-tutorial.
Stresses beyond those listed under âAbsolute Maximum Ratingsâ 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 = VCPVDD = +5V, VSGND = VPGND = 0, SHDN = VDD, C1 = C2 = 1µF, RL = â, resistive load referenced to ground, for
MAX13330 gain = -1.5V/V (internally set), for MAX13331 gain = -1.5V/V (RIN = 30kΩ, RFB = 45kΩ), TA = TJ = -40°C to +105°C, unless
otherwise noted. Typical values are at TA = +25°C, unless otherwise noted.) (Note 2)
