2 General description
The MLX90615 is an Infra Red thermometer for non
contact temperature measurements. Both the IR sensitive
thermopile detector chip and the signal conditioning chip are
integrated in the same TO-46 can package.
Thanks to its low noise amplifier, 16-bit ADC and
powerful DSP unit, a high accuracy and resolution of the
thermometer is achieved.
The thermometer is factory calibrated with the digital
SMBus compatible interface enabled. Readout resolution is
0.02°C.
