Dual 10-Bit, 20Msps, +3V, Low-Power ADC with Internal Reference and Multiplexed Parallel Outputs 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS ELECTRICAL CHARACTERISTICS (VDD = +3V, OVDD = +2.5V, 0.1µF and 1µF capacitors from REFP, REFN, and COM to GND; REFOUT connected to REFIN through a 10k Ω resistor, VIN = 2Vp-p (differential w.r.t. COM), CL = 10pF at digital outputs (Note 5), fCLK = 20MHz, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) 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.
