DC ELECTRICAL CHARACTERISTICS
(MAX3580 EV kit, V
CC
= +3.1V to +3.5V, GND = 0V, BB_AGC = RF_AGC = +2.85V, RF input terminated into a 75Ω load, BBI_ and
BBQ_ are open, no input signal, VCO active, registers set according to the specified default register conditions, T
A
= -40°C to
+85°C, unless otherwise specified. Typical values are at V
CC
= +3.3V, T
A
=+25°C, unless otherwise specified.) (Note 1)
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.
