Full Channel Performance Specifications
(continued)
Note 4:
The absolute maximum junction temperature (TJmax) for this device is 150
o
C. The maximum allowable power dissipation
is dictated by TJmax, the junction-to-ambient thermal resistance (*JA), and the ambient temperature (TA), and can be cal-
culated using the formula PDMAX = (TJmax - TA)/*JA. In the 48-pin LQFP, *JA is 69oC/W, so PDMAX = 1,811mW at 25oC
and 1,159 mW at the maximum operating ambient temperature of 70oC. Note that the power dissipation of this device
under normal operation will typically be about TBDmW. The values for maximum power dissipation listed above will be
reached only when the LM98503 is operated in a severe fault condition.
Note 5:
Human body model is 100pF capacitor discharged through a 1.5k
resistor. Machine model is 220pF discharged through
ZERO Ohms.
Note 6:
See AN450, “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 magnitude up to 500mV beyond the supply rails will not
damage this device. However, input errors will be generated If the input goes above AV+ and below AGND.
Note 8:
Note 9:
Typical figures are at TJ = 25
o
C, and represent most likely parametric norms
Test limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
