Digital infrared thermometer IC with narrow wavelength filter

The MLX90617 is a high-precision infrared thermometer designed for non-contact temperature measurements. It features a specific wavelength filter that enables it to detect infrared radiation from hot objects behind ceramic glass, making it suitable for applications like induction cooktops.

This sensor comes factory calibrated for a wide temperature range, measuring ambient temperatures from -0°C to +125°C and object temperatures from 70°C to 250°C. The MLX90617 achieves high accuracy and resolution thanks to its low-noise amplifier, 17-bit ADC, and powerful DSP.
