ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VDD = VCPVDD = +5V, VSGND = VPGND = 0, SHDN = VDD, C1 = C2 = 1µF, RL =

∞, resistive load referenced to ground, for

MAX13330 gain = -1.5V/V (internally set), for MAX13331 gain = -1.5V/V (RIN = 30k

Ω, RFB = 45kΩ), TA = TJ = -40°C to +105°C, unless

otherwise noted. Typical values are at TA = +25°C, unless otherwise noted.) (Note 2)

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.

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.
