Note 1.

Exceeding the absolute maximum rating may damage the device.

Note 2.

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

Note 3.

Devices are ESD sensitive. Handling precautions recommended.

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

Note 4.

Final test on outgoing product is performed at T

Note 5.

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

Note 6.

Accuracy specification does not include quantization noise, which may be as great as

Note 7.

T

Note 8.

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

Note 9.

This is the decimal representation of a binary data value.
