MLX90108 Electrical Specifications
All specifications are valid for Manchester, Biphase and PSK encoding, and for 2kbaud and 4kbaud and
8kbaud data rate options, Toper = -40°C to 85°C, Operating frequency = 120kHz (unless otherwise specified)

Notes:
Note (1): All specification values are tested 100%, or
guaranteed by characterization.
Note (2): Maximum supply voltage is generated by
forcing 10mA between coil and ground pin.
Note (3): Continuous (without POR restart) normal
reading of the 64bit ID on test set up as depicted
besides.
Note (4): Min = Vbottom (modulation on),
Max = Vtop (modulation off).

Note (5): Statistical spread on wafer basis within one lot is 3.5%. Temperature shift is typically -0.5% on -40°C,
and +1% at 85°C. On the MLX90108D a maximum Lot to lot spread of 20% is possible: average of a lot can vary
between 64 and 96pF.
