Features & Applications
The MLX90614ESF-DCI is a Part of MLX90614 Series  5.5 V 13.5 mA Gradient Compensated Infra Red Thermometer available in Through hole TO-39 Package.

It is used non contact temperature measuments. IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO-39 can. Integrated into the MLX90614 are a low noise amplifier, 17-bit ADC and powerful DSP unit thus achieving high accuracy and resolution of the thermometer.
