IR MEMS temp sensorTexas Instruments is enabling contactless temperature measurement in portable consumer electronics with a single-chip passive infrared (IR) MEMS temperature sensor. The TMP006 digital temperature sensor provides manufacturers of mobile devices, such as smart phones, tablets and notebooks, with the ability to accurately measure device case temperature using IR technology. It can also be used to measure temperature outside the device. It integrates an on-chip MEMS thermopile sensor, signal conditioning, a 16-bit analog-to-digital-converter (ADC), local temperature sensor and voltage references on a single 1.6-mm x 1.6-mm chip. It provides a complete digital solution for contactless temperature measurement that is 95 percent smaller than any other thermopile sensor. The sensor uses 240 uA quiescent current and 1 uA in shutdown mode – asserted to be a 90 percent less power than competitive solutions. The TMP006 supports a wide temperature range of -40 degrees to +125 degrees Celsius (C) with an accuracy of +/- 0.5 degree C (typical) on the local sensor and accuracy of +/- 1 degrees C (typical) for the passive IR sensor.
