Note 6: Minimum and maximum limits are guaranteed but may not be 100% tested.
Note 7: These supply voltages are calculated using the I
VPPSENSE
and I
VNNSENSE
values shown in the Electrical
Characteristics table. The typical voltage values shown are calculated using a R
VPP
and R
VNN
values without
any tolerance variation. The minimum and maximum voltage limits shown include either a +1% or –1% (+1%
for Over-voltage turn on and Under-voltage turn off, -1% for Over-voltage turn off and Under-voltage turn on)
variation of R
VPP
or R
VNN
off the nominal 562kohm and 1.69Mohm values. These voltage specifications are
examples to show both typical and worst case voltage ranges for the given R
VPP
and R
VNN
resistor values.
Please refer to the Application Information section for a more detailed description of how to calculate the over
and under voltage trip voltages for a given resistor value.
Note 8: The fact that the over-voltage specifications exceed the absolute maximum of +/-70V for the TDA1400 does
not imply that the part will work properly at these elevated supply voltages. It also does not imply that the
TDA1400 is tested or guaranteed at these supply voltages. The supply voltages are simply a calculation
based on the process spread of the I
VPPSENSE
and I
VNNSENSE
currents (see note 7). .
