Description

The ground return for the digital supply for the ADC12DL080's output

drivers. These pins should be connected to the system digital

23, 31, 40,

DRGND

ground, but not be connected in close proximity to the

50, 58

ADC12DL080's DGND or AGND pins. See LAYOUT AND

GROUNDING (Layout and Grounding) for more details.

(1)

All voltages are measured with respect to GND = AGND = DGND = 0V, unless otherwise specified.

(2)

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.

(3)

limited to 25 mA. The 50 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies

with an input current of 25 mA to two.

(4)

ambient temperature of 85°C. Note that the power consumption of this device under normal operation will typically be about 497 mW

(447 typical power consumption + 50 mW TTL output loading). The values for maximum power dissipation listed above will be reached

only when the device 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.

(5)

Human body model is 100 pF capacitor discharged through a 1.5 k

Ω resistor. Machine model is 220 pF discharged through 0Ω.
