Notes:
2. Exceeding the absolute maximum ratings may damage the device.
3. The device is not guaranteed to function outside its operating ratings. Final test on outgoing product is performed at TA = 25°C.
4. Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5kΩ in series with 100pF.
5. Specification for packaged product only.
6. Current into the /INT or DATA pins will result in self heating of the device. Sink current should be minimized for best accuracy.
7. Guaranteed by design over the operating temperature range. Not 100% production tested.
8. tINT and tCRIT are equal to tCONV.
9. TD is the temperature of the remote diode junction. Testing is performed using a single unit of one of the transistors listed in Table 8.
10. tCONV = tCONV(local) + tCONV(remote). Following the acquisition of either remote or local temperature data, the limit comparisons for that zone are
performed and the device status updated. Status bits will be set and /INT driven active, if applicable.
11. The interrupt reset propagation delay is dominated by the capacitance on the bus.
12. Accuracy specification does not include quantization noise, which may be up to ±1/2 LSB.
13. Tested at 10-bit resolution.
