Infrared thermometer IC has smarts for medical measurements

The Melexis MLX9061 is what the vendor claims is the first intelligent infrared thermometer integrated into the ultra small TO-46 package commonly used in the manufacture of ear thermometers. It provides a fully calibrated, digital-temperature reading via an infrared sensor integrated with a custom signal conditioning chip. The IC has advanced low-noise amplifiers, a 16-bit ADC, and powerful DSP unit in its signal conditioning chip.

Operating temperature range of -40°C to +85°C, with an extended object temperature range of -40°C to +115°C while maintaining a temperature resolution of 0.02°C. The MLX90615 has a high absolute accuracy of ±0.1°C in the critical temperature range of 36°C to 39°C. The 3V IC consumes 1 mA when operating and 2 μA in sleep mode.
