ABSOLUTE MAXIMUM RATINGS

DC ELECTRICAL CHARACTERISTICS

(MAX9986 Typical Application Circuit, VCC = +4.75V to +5.25V, no RF signal applied, IF+ and IF- outputs pulled up to VCC through

inductive chokes, R1 = 953Ω, R2 = 619Ω, TC = -40°C to +85°C, unless otherwise noted. Typical values are at VCC = +5V, TC =

+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.

VCC to GND ...........................................................-0.3V to +5.5V

IF+, IF-, LOBIAS, LOSEL, IFBIAS to GND...-0.3V to (VCC + 0.3V)

TAP ........................................................................-0.3V to +1.4V

LO1, LO2, LEXT to GND........................................-0.3V to +0.3V

RF, LO1, LO2 Input Power .............................................+12dBm

RF (RF is DC shorted to GND through a balun) .................50mA

Continuous Power Dissipation (TA = +70°C)
