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.

CAUTION! ESD SENSITIVE DEVICE

Electrical Characteristics

(MAX3580 EV kit, VCC = +3.1V to +3.5V, VGND = 0V, VBB_AGC = VRF_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, unless otherwise

specified. Typical values are at VCC = +3.3V, TA = +25°C, unless otherwise specified.) (Note 1)
