Stresses beyond those listed under âAbsolute Maximum Ratingsâ 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.
Package Thermal Characteristics (Note 1)
Ultra TQFN
Junction-to-Ambient Thermal Resistance (θJA)..........110.8°C/W
Junction-to-Case Thermal Resistance (θJC).............62.1°C/W
Note 1: 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.
Electrical Characteristics
(VDD = 2.2V to 3.6V, VREF = VDD, VOVDD = VDD. fSCLK = 48MHz, 50% duty cycle, 3Msps. CDOUT = 10pF, TA = -40°C to +125°C,
unless otherwise noted. Typical values are at TA = +25°C.)
