Notes:
1.
Absolute maximum ratings are limits beyond which operation
may cause permanent damage to the device. These are
stress ratings only; functional operation at or above these
limits is not implied. 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.
All voltages are measured with respect to GND, unless
otherwise specified.
When the input voltage (VIN) at any pin exceeds the power
supplies (VIN< (GND or GNDA) or VIN>V+, except for SST
and analog voltage inputs), the current at that pin should be
limited to 5mA. The 20mA maximum package input current
rating limits to number of pins that can safely exceed the
power supplies with an input current of 5mA to four.
The maximum power dissipation must be de-rated at elevated
temperatures and is dictated by TJmax,
θ
JA
and the ambient
temperature, T
. The maximum allowable power dissipation at
any temperature is PD = (TJmax - TA) /
θ
JA
. It must also take
into account self-heating that can adversely affect the
accuracy of internal sensors.
Human Body Model: 100pF capacitor discharged through a
1.5k
Ω
resistor into each pin. Machine Model: 200pF capacitor
discharged directly into each pin. Charged-Device Model is
per JESD22-C101C.

Notes:
6.
These specifications are guaranteed only for the test conditions listed.
7.
Accuracy (expressed in °C) = Difference between the aSC7531 reported temperature and the device temperature.
8.
The aSC7531 can be read at any time without interrupting the temperature conversion process.
9.
For the aSC7531A, calibration of the remote diode sensor input is set to meet the accuracy limits with a diode-connected 2N3904 that has
a non-ideality factor of 1.0046 with a series resistance of 0.6
. For the aSC7531B, calibration of the remote diode sensor input is set to
meet the accuracy limits with a CPU substrate diode that has a non-ideality factor of 1.009 with a series resistance of 4.52
.
10. Total monitoring cycle time for all temperature and analog input voltage measurements is 0.2 second.
11. TUE includes Offset, Gain and Linearity errors of the ADC.
