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