ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(VDD = +2.7V to +5.5V, GND = 0, VREF = VDD, RL = 5k, CL = 200pF, TA = TMIN to TMAX, unless otherwise noted. Typical values are
at VDD = +5V, TA = +25°C.) (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.
VDD, SCL, SDA to GND ............................................-0.3V to +6V
OUT_, REF, ADD to GND..............................-0.3V to VDD + 0.3V
Maximum Current into Any Pin............................................50mA
Continuous Power Dissipation (TA = +70°C)
8-Pin MAX (derate 4.5mW above +70°C) ...................362mW
Operating Temperature Range ...........................-40°C to +85°C
Storage Temperature Range .............................-65°C to +150°C
Maximum Junction Temperature .....................................+150°C
Lead Temperature (soldering, 10s) .................................+300°C
