Note 1.
The device is not guaranteed to function outside its operating range.
Note 2.
Final test on outgoing product is performed at T
A
= 25°C.
Note 3.
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 5.
Note 4.
Current into the DATA pin 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.
Accuracy specifications do not include quantization noise which may be up to ± 0.5LSB.
Note 7.
Devices are ESD sensitive. Observe appropriate handling precautions.
