Texas Instruments TMP006 Infrared MEMS Temperature Sensor

Texas Instruments introduced the TMP006 passive infrared (IR) MEMS temperature sensor. The TMP006 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. The single-chip digital temperature sensor measures device case temperature using IR technology. The TMP006 is available now with a suggested retail price of $1.50 (1,000-unit quantities). The TI chip is ideal for mobile devices, such as smartphones, tablets and notebooks.
