World's first single-chip digital IR MEMS temperature sensor

Enables contactless temperature measurement in portable and consumer electronic applications

Developed through TI's expertise in MEMS technology, the TMP006 is the first of a new class of ultra-small, low power, and low cost passive infrared temperature sensors. It has 90% lower power consumption and is more than 95% smaller than existing solutions, making contactless temperature measurement possible in completely new markets and applications.

Key features and benefits

  • Complete single-chip digital solution, including integrated MEMS thermopile sensor, signal conditioning, ADC and local temperature reference
  • The first thermopile designed for portable applications, thanks to an ultra-thin (0.625 max) profile
  • Low power design extends the life of battery powered applications
