Both the IR sensitive thermopile detector chip and the signal conditioning chip are integrated in the same TO-46 can package. J1 MLX90615 4 U1 Vss Thanks to its low noise amplifier, 16-bit ADC and SCL powerful DSP unit, a high accuracy and resolution of the SDA SDA SCL 1 3 thermometer is achieved. Vdd The thermometer is factory calibrated with the digital Vdd C1 SMBus compatible interface enabled. Readout resolution is 2 GND 0.02C. 0.1uF CON1 C1 value and type may differ in different applications for optimum EMC Figure 1 Typical application schematics MLX90615 connection to SMBus 3901090615 Page 1 of 32 Data Sheet Rev 005 08 November 2013 MLX90615 Infra Red Thermometer General description (continued) 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 0.02C. The values are accessible by 2 wire serial SMBus compatible protocol with a resolution of 0.02C or via a 10-bit PWM (Pulse Width Modulated) signal from the device. The MLX90615 is factory calibrated in standard temperature ranges from: -40...85C for the ambient temperature and from -40...115C 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 (5.5m 14m 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. 3901090615 Page 2 of 32 Data Sheet Rev 005 08 November 2013
