Clamping the Output Voltage
The MLX90215 has a 2-bit CLAMP feature which
allows Four output voltage options. The CLAMP
feature is independent of the gain, and will not effect
sensitivity of the device. The table below illustrates
limits for each of the four options.

Application Comments
The following is a list of recommended operating
parameters that will help to ensure the accuracy and
stability of the MLX90215. These are not the absolute
programming limits of the device.

function enabled.
3.) Best linearity of sensitivity is obtained when the
4.) Best temperature stability is realized when the
5.) The Test/Readback pin is for diagnostic use only.
Installation Comments
1.) Avoid mechanical stress on leads or package.
2.) CMOS products are static sensitive devices, please
3.) Observe temperature limits during soldering.
