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
A
or DR V
D
), the current at that pin
should be 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.
Note 4:
The absolute maximum junction temperature (T
J
max) for this device is 150C. The maximum allowable power dissipation is dictated by T
J
max, the
junction-to-ambient thermal resistance (
θ
JA
), and the ambient temperature (T
A
), and can be calculated using the formula P
D
MAX = (T
J
max T
A
) /
θ
JA
. In the 24-pin
TSSOP,
θ
JA
is 92C/W, so P
D
MAX = 1,358 mW at 25C and 435 mW at the maximum operating ambient temperature of 85C. Note that the power consumption of
this device under normal operation will typically be about 180 mW (88 mW quiescent power +12 mW reference ladder power). The values for maximum power
dissipation listed above will be reached only when theADC08060 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 k
resistor. Machine model is 220 pF discharged through ZERO Ohms.
Note 6:
See AN-450, “Surface Mounting Methods and Their Effect on Product Reliability”, or the section entitled “Surface Mount” found in any post 1986 National
Semiconductor Linear Data Book, for other methods of soldering surface mount devices.
Note 7:
The analog inputs are protected as shown below. Input voltage magnitudes up to V
A
+ 300 mV or to 300 mV below GND will not damage this device.
However, errors in theA/D conversion can occur if the input goes above DR V
D
or below GND by more than 100 mV. For example, if V
A
is 2.7V
DC
the full-scale input
voltage must be
≤
2.6V
DC
to ensure accurate conversions.
20006207
Note 8:
To guarantee accuracy, it is required that V
A
and DR V
D
be well bypassed. Each supply pin must be decoupled with separate bypass capacitors.
Note 9:
Typical figures are at T
J
= 25C, and represent most likely parametric norms. Test limits are guaranteed to National’s AOQL (Average Outgoing Quality
Level).
