cycle. Boldface limits apply for T
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: All voltages are measured with respect to GND = AGND = DR GND = 0V, unless otherwise specified.
Note 3: When the input voltage at any pin exceeds the power supplies (that is, less than AGND or DR GND, or greater than V

25 mA to two.

this device under normal operation will typically be about 49 mW (40 mW quiescent power + 4 mW reference ladder power + 5 mW to drive the output bus
capacitance). The values for maximum power dissipation listed above will be reached only when the ADC08L060 is operated in a severe fault condition (e.g., when
input or output pins are driven beyond the power supply voltages, or the power supply polarity is reversed). Obviously, such conditions should always be avoided.
Note 5: Human body model is 100 pF capacitor discharged through a 1.5 kΩ resistor. Machine model is 220 pF discharged through ZERO Ohms.
Note 6: See AN-450, “Surface Mounting Methods and Their Effect on Product Reliability”.
