Smart, micro-machined Infrared Thermometer for medical needs

Melexis launched the MLX90615, the world's first integrated intelligent infrared thermometer. This non-contact thermometer delivers a fully calibrated digital temperature reading achieved by integrating an infrared sensor with a custom signal-conditioning chip.

The sensing element is a silicon chip with a thin, micro-machined membrane, heated by the infrared radiation of the object. A signal-conditioning chip amplifies and digitizes the minute voltages generated by the thermocouples on the sensor membrane and calculates the object temperature, using factory set calibration parameters stored in the memory of the chip. The key features are,

1. The digitized temperature is fully linearized and compensates for ambient temperature.
2. The MLX90615 applies advanced low noise amplifiers, a 16-bit ADC, with a powerful DSP unit in its signal-conditioning chip.
3. A wide operating temperature range of -40°C to +85°C
4. An extended object temperature range of -40°C to +115°C
5. A temperature resolution of 0.02°C
6. Absolute accuracy of ±0.1°C in the critical temperature range of 36°C to 39°C.
7. Uses a 3 Volt supply voltage and consume less then 1 mA in normal operation.
8. Has a "sleep" mode during which the current consumption can be as low as 2µA.
