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