Note 1. The device is not guaranteed to function outside its operating range.
Note 2. Final test on outgoing product is performed at T
Note 3. T
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.
