_______________________________________________________________________________________
ABSOLUTE MAXIMUM RATINGS
DC ELECTRICAL CHARACTERISTICS
(MAX9994 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 = 806
Ω, R2 = 549Ω, 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)
20-Pin Thin QFN-EP (derate 20mW/°C above +70°C)..............1.8W
θJA .................................................................................+38°C/W
θJC ...................................................................................+8°C/W
Operating Temperature Range (Note A) ....TC = -40°C to +85°C
Junction Temperature ......................................................+150°C
Storage Temperature Range .............................-65°C to +150°C
Lead Temperature (soldering 10s) ..................................+300°C
Note A: TC is the temperature on the exposed paddle of the package.
