Stresses beyond those listed under âAbsolute Maximum Ratingsâ 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
(AVCC = OVCC = 1.8V, VAGND = VOGND = 0, fSAMPLE = 170MHz, differential sine-wave clock input drive, 0.1µF capacitor on REFIO,
internal reference, digital output pins differential RL = 100Ω ±1%, CL = 5pF, TA = TMIN to TMAX, unless otherwise noted. ⥠+25°C
guaranteed by production test, < +25°C guaranteed by design and characterization. Typical values are at TA = +25°C.)
