AAF, ADC, and CWD Beamformer)
Absolute Maximum Ratings
VCC3, VCC5 to GND..............................................-0.3V to +5.5V
AVDD, OVDD to GND...........................................-0.3V to +2.1V
VCC5 - VCC3 .................................................................... > -0.3V
VREF, LO+/-, GC+/- to GND.....................-0.3V to (VCC3 + 0.3V)
CI+/-, CQ+/- to GND..............................................-0.3V to +13V
ZF_, IN_, AG to GND................................-0.3V to (VCC5 + 0.3V)
INC_............................................................................ ±20mA DC
IN_ to AG...............................................................-0.6V to +0.6V
REFIO, CLKIN+/-, LOON to
GND............ -0.3V to the lower of (VAVDD + 0.3V) and +2.1V
OUT+/-, SDIO, SCLK, CS, CLKOUT+/-, FRAME+/-,
SHDN, CWD to GND..... -0.3V to the lower of (VOVDD + 0.3V)
and +2.1V
CI+/-, CQ+/-, VCC5, VCC3, AVDD/OVDD, VREF analog and
digital control signals must be applied in this order.
Input Differential Voltage................................ 2.0VP-P differential
Continuous Power Dissipation (TA = +70NC)
144-Bump CTBGA (derate 33.3mW/NC above +70NC).....3200mW
Operating Case Temperature Range (Note 1).....0NC to +70NC
Junction Temperature......................................................+150NC
Storage Temperature Range............................. -40NC to +150NC
Soldering Temperature (reflow).......................................+260NC
Note 1: TC is the temperature on the bump of the package. TA is the ambient temperature of the device and PCB.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion 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.
Package Thermal Characteristics (Note 2)
Junction-to-Ambient Thermal Resistance (qJA)...............25°C/W
Junction-to-Case Thermal Resistance (qJC)...................7.7°C/W
Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
