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.

Note 6.

Current into this pin will result in self-heating of the MIC384. Sink current should be minimized for best accuracy.

Note 7.

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