Description:
The MLX90615 is built from 2 chips, the Infra Red thermopile detector and the signal conditioning chip
MLX90325, specially designed by Melexis to process the output of IR sensor. The device is available in an industry standard TO-46 package.
Thanks to the low noise amplifier, high resolution 16-bit ADC and powerful DSP unit of the MLX90325,
Melexis is able to deliver a high accuracy and high resolution infrared thermometer. The calculated object
and ambient temperatures are available in the RAM memory of the MLX90325 with a resolution of 0.02 °C.
The values are accessible by 2 wire serial SMBus compatible protocol with a resolution of 0.02°C or via a 10-
bit PWM (Pulse Width Modulated) signal from the device.
The MLX90615 is factory calibrated in standard temperature ranges from: -40 to 85°C for the ambient
temperature and from -40 to 115°C for the object temperature.
As a standard, the MLX90615 is delivered with a programmed object emissivity of 1. It can be easily
customized by the customer for any other emissivity in the range 0.1-1.0 without the need of recalibration with
a black body.
The MLX90615 can be battery powered.
An optical filter (5.5μm to 14μm long-wave pass) that cuts off the visible and near infra-red radiant flux is
integrated in the package to make the sensor insensitive to visible light.
