2 / 24 page Relative Accuracy (Note 2) Low-Power, 8-Channel, Serial 12-Bit ADCs 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS ELECTRICAL CHARACTERISTICS (VDD = 5V ±5%; VSS = 0V or -5V; fCLK = 2.0MHz, external clock (50% duty cycle); 15 clocks/conversion cycle (133ksps); MAX186— 4.7µF capacitor at VREF pin; MAX188—external reference, VREF = 4.096V applied to VREF pin; 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.
