ABSOLUTE MAXIMUM RATINGS
DC ELECTRICAL CHARACTERISTICS
(VCC = +2.7V to +5.5V, PIN = -25dBm, IN driven from a 50 source, OUT_ LC-matched to 50, TA = TMIN to TMAX, unless otherwise
noted. Typical values are at VCC = +3V, TA = +25°C.) (Note 1)
AC ELECTRICAL CHARACTERISTICS—MAX2472
(
Typical Operating Circuits, VCC = +3V, PIN = -25dBm, IN driven from a 50 source, OUT1 and OUT2 LC matched to 50, TA =
+25°C, unless otherwise noted.)
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.
