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
A
= TBD°C.
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.
Current into this pin will result in self-heating of the MIC384. Sink current should be minimized for best accuracy.
Guaranteed by design over the operating temperature range. Not 100% production tested.
t
CONV
= t
CONV0
+(2 X t
CONV1
). t
CONV0
is the conversion time for the local zone; t
CONV1
is the conversion time for the remote zones.`
