Notes:

2.

Exceeding the absolute maximum ratings may damage the device.

3.

4.

Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5k

Ω in series with 100pF.

5.

Specification for packaged product only.

6.

Current into the DATA pin 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.

Accuracy specification does not include quantization noise, which may be up to ±1/2 LSB.
