The TMP006 and TMP006B use a two-wire interface (I2C and SMBus compatible), and are specified over the die temperature range of –40°C to +125°C. The TMP006 and TMP006B measure object temperatures over a range limited only by the maximum sensor voltage (5.12 mV). The TMP006 and TMP006B contain registers for holding configuration information, temperature measurement results, and sensor voltage measurement. Die temperature and sensor voltage measurements are used to calculate the object temperature. The TMP006 and TMP006B provide both die temperature and thermopile sensor voltage outputs in a small DSBGA chip-scale package. The die temperature sensor in both the TMP006 and TMP006B is integrated on- chip; the thermal path runs through the DSBGA solder balls. The low thermal resistance of the solder balls provides the thermal path to maintain the chip at the temperature of the die environment. The top side of the DSBGA package must face the object that is being measured with an unobstructed view in order to accurately measure the temperature. Refer to the user guide TMP006 Layout and Assembly Guidelines (SBOU108) for more details. 8.2 Functional Block Diagram 8.3 Feature Description The TMP006 and TMP006B sense the IR radiation emitted by all objects. The spectrum of the radiation depends only on the temperature and is given by Planck’s law, as shown in Equation 1: where • h = Planck’s constant • c = speed of light • kB = Boltzmann’s constant • λ = wavelength in microns (1) 8 Submit Documentation Feedback Copyright © 2011–2015, Texas Instruments Incorporated Product Folder Links: TMP006 TMP006B |
