Maxim Integrated
ABSOLUTE MAXIMUM RATINGS
RECOMMENDED DC OPERATING CONDITIONS
(VDD = +3.3V, VDDA = +5.0V, TA = +25°C, unless otherwise noted.) (Note 1)
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.
Voltage Range on VDD Relative to GND ...............-0.5V to +6.5V
Voltage Range on VDDA Relative to PGND ...........-0.5V to +6.5V
Voltage Range on CP1, CP2, and VUP
Relative to PGND...............................................-0.5V to +7.5V
Voltage Range on All Other Pins
Relative to GND......................................-0.5V to (VDD + 0.5V)
Maximum Junction Temperature .....................................+125°C
Maximum Power Dissipation (TA = -40°C to +85°C) .......700mW
Storage Temperature Range .............................-55°C to +150°C
Soldering Temperature.........Refer to the IPC/JEDEC J-STD-020
Specification.
