Integrated infrared thermometer delivers medical accuracy over a wide operating range

One of the most prominent applications of Infra Red thermometers has been the fever measurement of humans. There are two main types of IR fever thermometers: the ear thermometers and forehead thermometers. For these medical applications, a measurement accuracy of ±0.1C is needed. Often such accuracy can only be achieved in small operating temperature ranges and under precisely controlled laboratory conditions.

Last year Melexis introduced the MLX90614 family of digital integrated temperature sensors. This small and cost effective non-contact thermometer delivers a fully calibrated, digital infrared temperature reading. An infrared sensor and a custom signal conditioning chip are integrated in one TO-can package.

Recently, Melexis enlarged the MLX90614 family with the MLX90614DAA. This 3 Volt device delivers the ±0.1C measurement accuracy in the object temperature range of 36C - 39C and the wide ambient temperature range 20C - 30C. The sleep mode option with a sleep current in the order of µA make this device highly suited for battery operated applications.

The MLX90614 family is qualified in accordance to AECQ100 and is ROHS compatible. It can be soldered up to 260°C according to JEDEC 020C Production quantities of this high accuracy integrated thermometer are available now. The MLX90614EAF-DAA is priced at 5.2 Euro/piece at 1,000 pieces quantity.
