ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(VDD = +2.7V to +3.6V (MAX1117), VDD = +4.5V to +5.5V (MAX1119), VDD = REF = +2.7V to +5.5V (MAX1118),TA = TMIN to TMAX,
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.
VDD to GND ...........................................................-0.3V to +6.0V
CH0,CH1, REF to GND...............................-0.3V to (VDD + 0.3V)
Digital Output to GND ................................-0.3V to (VDD + 0.3V)
Digital Input to GND ..............................................-0.3V to +6.0V
Maximum Current into Any Pin .........................................±50mA
Continuous Power Dissipation (TA = +70°C)
8-Pin SOT23 (derate 8.9mW/°C above +70°C)............714mW
Operating Temperature Range
