ELECTRICAL CHARACTERISTICS (continued)
(V+ = +5V ±5%, V DD = +2.7V to +5.25V, V REFIN+ = +2.50V, REFIN- = AGND, f CLKIN = 2.4576MHz, T A = T MIN to T MAX , unless other-
wise noted. Typical values are at T A = +25°C.)

ANALOG POWER-SUPPLY CURRENT (Measured with digital inputs at either DGND or V DD , external CLKIN, burn-out and auxil-
iary currents disabled, X2CLK = 0, CLK = 0 for 1.024MHz, CLK = 1 for 2.4576MHz.)
DIGITAL POWER-SUPPLY CURRENT (Measured with digital inputs at either DGND or V DD , external CLKIN, burn-out and auxiliary
currents disabled, X2CLK = 0, CLK = 0 for 1.024MHz, CLK = 1 for 2.4576MHz.)
