Melexis  

Addresses growing demands seen across numerous applications for thermal analysis. This infrared (IR) sensor offers a cost-effective alternative to more expensive high-end thermal cameras.

This 32x24 pixel device is suited to safety and convenience applications that include fire prevention systems, smart buildings, intelligent lighting, IP/surveillance cameras, HVAC equipment and vehicle seat occupancy detection.

It has a -40°C to 85°C operational temperature range and can measure object temperatures between -40°C and 300°C. Maintaining high levels of precision across its full measurement scale, this infrared sensor delivers a typical target object temperature accuracy of ±1°C.
It also exhibits superior noise performance.

Unlike microbolometer alternatives, the sensor does not need frequent re-calibration, thus ensuring continuous monitoring and lowering system cost. The Melexis MLX90640 is supplied in a compact, 4-pin TO39 package incorporating the requisite optics. An I²C-compatible digital interface simplifies integration.

• -40 to 85°C operational temperature range, allows deployment in difficult industrial environments
• Can measure object temperature between -40 to 300°C
• A typical target object temperature accuracy of 1°, precision across its full measurement scale
• NETD of just 0.1K RMS at a 1Hz refresh rate
• No re-calibration needed to specific temperature requirements ensuring greater convenience and lowering operational expense
• Two different field of view (FoV) options: standard 55°x35° and 110°x75° wide angle
• 4-pin TO39 package incorporating the requisite optics
• I²C compatible digital interface, simplifying integration

The MLX75027 automotive time-of-flight sensor supports up to VGA resolution. The sensor, alongside the 90 nm BSI VGA pixel array, provides the control signals for the illumination unit and has a MIPI CSI-2 high speed serial interface to stream data to the host processor.

Thanks to a simple supply system, with only three positive voltage domains, the sensor simplifies the design of the supply unit and together with a low power dissipation allows a very compact 3D camera.

The MLX75027 supports up to 100 MHz illumination modulation frequency, which makes it well suited for VCSELs illumination and has a built-in temperature sensor.
