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.

2. Human Body Model: 100pF capacitor discharged through

a 1.5kΩ resistor into each pin. Machine Model: 200pF

capacitor discharged directly into each pin. Charged

Device Model is per JESD22-C101C.

3. These specifications are guaranteed only for the test

conditions listed.

4. Accuracy (expressed in °C) = Difference between the

aSC7511 reported output temperature and the

temperature being measured.

5. Guaranteed by characterization but not production tested.

6. The accuracy of the aSC7511 is guaranteed when using

the thermal diode of a processor or any thermal diode with

a non-ideality of 1.008 and internal series resistance of

3.52Ω. When using a 2N3904 type transistor as a thermal

diode the error band will be typically shifted depending on

transistor characteristics.

7. The aSC7511 can be read at any time without interrupting

the temperature conversion process.
