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
A
= TBD癈.
Note 5. T
D
is the temperature of the remote diode junction. Testing is performed using a single unit of one of the transistors listed in Table 6.
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.
Note 8. t
CONV
= t
CONV0
+(2 X t
CONV1
). t
CONV0
is the conversion time for the local zone; t

is the conversion time for the remote zones.`
Note 9. Accuracy specication does not include quantization noise, which may be as great as ?/SPAN>
