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.
ELECTRICAL CHARACTERISTICS
(VDD = +2.7V to +3.6V, VREF = +2.5V for MAX1087/MAX1089, or VDD = +4.75V to +5.25V, VREF = +4.096V for MAX1086/MAX1088, 0.1µF capacitor at REF, fSCLK = 8MHz (50% duty cycle), AIN- = GND for MAX1088/MAX1089. TA = TMIN to TMAX, unless otherwise noted. Typical values at TA = +25°C.)
