Note 1
. Exceeding the absolute maximum rating may damage the device.
Note 2.
The device is not guaranteed to function outside its operating range. Final test on outgoing product is performed at T
A
= 25°C.
Note 3.
Devices are ESD sensitive. Handling precautions recommended.
Note 4.
Current into the /INT or DATA pins will result in self heating of the device. Sink current should be minimized for best accuracy.
Note 5.
Guaranteed by design over the operating temperature range. Not 100% production tested.
Note 6.

.
Note 7.
T
D
is the temperature of the remote diode junction. Testing is performed using a single unit of one of the transistors listed in Table 8.
Note 8.
t
= t
(local) + t
(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.
Note 9.
The interrupt reset propogation delay is dominated by the capacitance on the bus.
Note 10.
Accuracy specification does not include quantization noise, which may be up to ±
1
/
2
LSB.
Note 11.
Tested at 10-bit resolution.
