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.
ELECTRICAL CHARACTERISTICS
(VDD = +2.7V to +5.25V; COM = 0; fSCLK = 2.0MHz; external clock (50% duty cycle); 15 clocks/conversion cycle (133ksps);
MAX149—4.7FF capacitor at VREF pin; MAX148—external reference, VREF = 2.500V applied to VREF pin; TA = TMIN to TMAX, unless
otherwise noted.)
