Exceeding the absolute maximum rating may damage the device.

The device is not guaranteed to function outside its operating rating.

Devices are ESD sensitive. Handling precautions recommended.

Human body model: 1.5k in series with 100pF. Machine model: 200pF, no series resistance.

Final test on outgoing product is performed at TA = TBD°C.

Guaranteed by design over the operating temperature range. Not 100% production tested.

Accuracy specification does not include quantization noise, which may be as great as ±1⁄2LSB (±1⁄4°C).

TD is the temperature of the remote diode junction. Testing is performed using a single unit of one of the transistors listed in Table 5.

Current into the INT pin will result in self-heating of the MIC184. INT pin current should be minimized for best accuracy.

This is the decimal representation of a binary data value.
